There are various types of resin for fluoropolymer coatings, depending on the application environment. At Yoshida SKT, we specify materials and processing based on the product number. 'HBA-838' is a type of PFA coating. By processing it to a thicker film, it results in a coating without pinholes, making it suitable for applications that require corrosion resistance. 【What is PFA (Perfluoroalkoxyalkane Polymer)?】 PFA is an improved resin of PTFE, with the same continuous use temperature of 260°C. Its melting point is around 310°C, and it has a lower thermal melt viscosity than PTFE, allowing for a continuous film with fewer pinholes that could not be achieved with PTFE during coating. As a corrosion-resistant coating, it has the best performance among fluoropolymer coatings. Additionally, PFA can exhibit superior non-stick properties compared to PTFE depending on the substrate, making it widely used for non-stick and release coatings. *For more details, please download the materials or contact us.

■Low Friction and Sliding Properties of Fluoropolymer (PTFE) Fluoropolymers have a low coefficient of friction and are used for solid lubrication. PTFE is structured such that fluorine atoms surround carbon atoms without gaps. The free energy of the fluorine atoms on the molecular surface is low, and the molecules have the characteristic of extremely low polarity in their target structure. The low coefficient of friction of PTFE is believed to be influenced by this type of molecular structure. ■Reasons for the Low Coefficient of Friction of Fluoropolymer PTFE - The strong atomic bonds within PTFE molecules reduce the intermolecular forces with the contacting material. - Friction (sliding) causes PTFE molecules to adhere slightly to the counterpart material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with minimal irregularities. - The orientation of PTFE molecules makes it easier to alleviate frictional resistance. For these reasons, fluoropolymer PTFE is considered to have excellent lubricating properties. For more details, please download the materials or contact us.

Types and Characteristics of Representative Fluororesins ■Resin Name PTFE (Polytetrafluoroethylene) ■Characteristics It has the highest continuous use temperature of 260°C, and is excellent in heat resistance, non-stick properties, and low friction characteristics. It has a high melt viscosity, making common molding methods for thermoplastic resins unsuitable. ■Also Known As Tetrafluoroethylene, 4F ■Resin Name PFA (Perfluoroalkoxyalkane Polymer) ■Characteristics An improved resin of PTFE, it has the same continuous use temperature of 260°C. It has a low thermal melt viscosity, allowing processing using molding methods for thermoplastic resins such as injection molding and extrusion. ■Resin Name FEP (Perfluoroethylene Propylene Copolymer) ■Characteristics An improved resin of PTFE, but with lower heat resistance than PTFE. Similar to PFA, it can be processed using molding methods for thermoplastic resins. ■Also Known As 4F6F, Tetrahexafluoride

■What "Non-Stick Properties" of Fluoropolymer Means Non-stick properties refer to the characteristic of being easy to release and not adhere, or to adhere less, even to strongly adhesive substances. For example, fluoropolymers excel in water and oil repellency, have a large contact angle, and possess a molecular structure that makes them difficult to wet. The measure of wettability, known as "critical surface tension (γc)," is extremely low for fluoropolymers, making it easy for liquids to bead up and difficult for them to wet the surface. Coatings that utilize this functionality are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. *For detailed information on non-stick properties, please download the PDF or contact us.*

■Chemical Resistance of Fluororesin Fluororesin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for High Chemical Resistance A major reason for the excellent chemical resistance of fluororesin is its stable molecular structure. Fluororesin is a high molecular polymer with a linear molecular structure formed by the bonding of carbon atoms and fluorine atoms. The bond energy between carbon and fluorine atoms (C-F) is very strong among chemical bonds, and furthermore, the C-C bond sections between carbon atoms are tightly covered by fluorine atoms in a helical manner. Therefore, it remains inert when in contact with chemicals or solvents, and does not degrade or dissolve as a resin, which means it has excellent chemical resistance. ■Applications of Fluororesin's Chemical Resistance - Various gaskets - Packing materials - Piping and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

■What is the "10under" Thin Film Fluoropolymer Coating? Conventional fluoropolymer coatings can be challenging to apply when dimensional stability of the substrate is a priority, particularly in terms of film thickness. Yoshida SKT has been working on development to meet these needs and has announced the "Thin Film Fluoropolymer Coating '10under.'" ■Features of 10under - Non-stick properties equivalent to standard fluoropolymer coatings - Capable of thin film processing of approximately 10μm, reducing dimensional changes - While being a thin film, it minimizes transparency *For more details, please download the materials or contact us.

**Types and Characteristics of Coatings** ■ PTFE Coating The continuous use temperature is the highest at 260°C, and it excels not only in heat resistance but also in non-stick and low friction properties. ■ PFA Coating It has the same continuous use temperature of 260°C as PTFE. It has a low thermal melt viscosity and is used as an anti-corrosion coating and non-stick coating. ■ FEP Coating Its heat resistance is lower at 200°C compared to PTFE. It provides a smooth surface with fewer pinholes in the coating. **Characteristics of Coatings** ■ Non-Stick Property It has the property of not adhering or being difficult to adhere to strongly adhesive substances. ■ Water and Oil Repellency It repels water and oil well even when they come into contact with the surface. ■ Heat and Cold Resistance Among resins, it has high heat resistance and can withstand high temperatures (260°C). ■ Low Friction Property It is very slippery and has excellent lubricating properties. ■ Chemical Resistance It is rarely affected or corroded by chemical substances such as acids and alkalis. ■ Electrical Properties It has high insulation strength (resistance to electrical breakdown), volume resistivity, and surface resistivity, making it excellent in electrical insulation. *For more details, please download the PDF or contact us.*

■What is corrosion-resistant coating? It is a coating that can protect the substrate, mainly metal tanks and pipes, from chemicals. Corrosion resistance refers to the property of being less prone to corrosion reactions and oxidation. By coating materials that excel in chemical resistance, corrosion resistance can be imparted to the substrate. Coatings that are relatively thick are referred to as "lining," and they are also called corrosion-resistant linings or anti-corrosion linings. Lining materials include resins, rubber, and glass, and in environments that are relatively corrosive or reactive, fluororesins, which excel in chemical resistance and heat resistance, are often chosen. Fluororesins can provide high corrosion resistance by utilizing excellent coating technology to create a pinhole-free finish. ▼ "Protecting the substrate from chemicals!"

Fluororesin coating can experience wear and peeling depending on the application, environment, and conditions. In such cases, it is possible to strip the coating and reprocess it. Reprocessing places a greater burden on the substrate compared to the initial processing, so consultation according to the application is necessary. 【Overview of Processing Steps】 ■Receiving the Substrate ○ Inspection of the substrate is conducted. ■Preheating ○ The substrate is heated in a furnace to thermally decompose oils, dirt, and fluororesin. ■Surface Preparation ・Blasting ○ The processing surface is blasted to remove rust and dirt, and to create a moderately rough surface. ■Primer Coating ○ A primer that enhances adhesion between the substrate and fluororesin is applied. ■Baking ○ The primer is cured. ■Coating ・Powder Coating ○ Fluororesin powder is applied using a special coating machine. ・Enamel Coating ○ Fluororesin enamel is applied either by machine or manually. ■Baking ○ The fluororesin is heated and melted to form a coating. ■Inspection ○ After processing is complete, an inspection is conducted to ensure that the processing meets specifications and agreements. For inquiries regarding reprocessing, please contact Yoshida SKT.

When using a household frying pan for a long time, the fluoropolymer coating may peel off or wear down, leading to sticking issues. The fluoropolymer coating can be removed and reprocessed. However, household frying pans are not designed with reprocessing in mind, which brings both advantages and disadvantages. ■ Advantages - The coating of a beloved cooking tool is renewed, restoring the non-stick properties and ease of maintenance similar to that of a new product. - There is no need to buy new equipment, and disposing of the old frying pan is not a problem. ■ Disadvantages - Reprocessing requires high-temperature heat treatment (over 400°C), necessitating the removal of handles made of resin or plastic. (If they cannot be removed, reprocessing is generally not possible.) - A frying pan that has been used for a long time may have corrosion on the metal parts, and even if the coating is reprocessed, it may not return to a like-new condition. - Especially in cases where the metal thickness is thin, reprocessing may cause distortion and deformation. - There may be adverse effects on the exterior, resulting in a poor appearance. As such, reprocessing has many disadvantages as well as advantages, so caution is necessary when it comes to household cooking utensils.

Fluoropolymer coatings are used in numerous industries, including: - Automotive parts - Semiconductor - Aerospace - Chemical industry - Medical and pharmaceutical - Food industry, among others Currently, a regulatory proposal is being considered within the EU to minimize the emissions of PFAS. ■ Target of the regulatory proposal Fluorine-based surface treatment agents: water and oil repellents, release agents, fluoropolymer-containing plating, etc. Coating materials: PTFE, PFA, FEP, ETFE, and other fluoropolymers (for applications such as corrosion-resistant lining, non-stick, lubrication, etc.) Molded and processed products: PTFE, PFA, FEP, ETFE, and other fluoropolymers (lining sheets, fabric sheets, etc.) Fluorine-based surfactants, fluorine-based oils, low molecular weight PTFE, fluorine-based molding aids, etc. The current regulatory proposal includes fluoropolymers, which are considered extremely stable and pose no toxicological or environmental concerns, and there is a possibility that fluoropolymer coatings may also be subject to regulation.

"NYK-01" and "NYK-01-C" are both product numbers for the bi-coat processed by Yoshida SKT. The "NYK" series is a surface treatment that combines a nickel-based metal coating with fluororesin. The main difference between "NYK-01" and "NYK-01-C" is the difference in surface roughness. Surface roughness varies depending on the surface processing condition of each substrate, but typically "NYK-01-C" has a rougher finish. Additionally, there are various product numbers such as "NYK-01-A" and "NYK-01-D" that differ in surface roughness adjustments. In the bi-coat, the first three letters of the alphabet (NYK) indicate the type of inorganic surface treatment, while the last two digits represent the type of organic surface treatment. 01 represents the fluorine-based treatment as part of the 01 series. *For more details, please contact us.*

This explains the differences in characteristics between the fluoropolymer "PTFE" and "ETFE." ■Resin Name PTFE (Polytetrafluoroethylene) ■Characteristics It is the first resin discovered and developed among fluoropolymers. It has a continuous use temperature of 260°C, excellent heat resistance, low friction properties, and non-stick characteristics. Although it has a high melting viscosity, making injection molding difficult, it is used as a coating for frying pans and hot plates. ■Resin Name ETFE (Ethylene Tetrafluoroethylene Copolymer) ■Characteristics Unlike perfluorinated fluoropolymers, ETFE contains hydrogen atoms (H) in its molecular structure. Therefore, its chemical resistance and heat resistance are lower compared to PTFE and FEP, with a continuous use temperature of 150°C compared to PTFE's 260°C. On the other hand, ETFE has high mechanical strength and can be processed at low melting points, making it suitable for applications requiring corrosion lining and wear resistance. *For more details, please click on "PDF Download" or feel free to contact us.*

Fluoropolymer refers to a type of polymer that contains fluorine atoms as a major component. Fluorine is a very distinctive element, and its properties are prominently reflected in the polymer. Below, I will explain the main characteristics and common applications of fluoropolymers in detail. ■Characteristics Very low adhesion Fluoropolymers are generally very smooth and have almost no adhesion, which is why they are known as "non-stick" or "non-adhesive." High chemical resistance Fluoropolymers possess excellent chemical resistance. They show resistance to many corrosive substances and solvents, and have chemically stable properties. This makes them suitable for applications such as chemical containers, piping, and gaskets. High heat resistance Fluoropolymers have the ability to withstand high temperatures. In particular, PTFE can endure very high temperatures (around 260°C or 500°F). This property makes them suitable for applications that require use under high-temperature conditions. Electrical insulation Fluoropolymers have excellent electrical insulation properties. This is one of the reasons they are widely used as insulating materials for electronic components and cables.

Fluoroelastomers have C-F bonds in their copolymer structure, providing excellent chemical resistance, oil resistance, and durability among rubbers. A representative example is FKM. On the other hand, fluoropolymers are plastics that contain fluorine atoms in their structure, such as PTFE, FEP, and PFA. ■Differences in Characteristics 【Fluoroelastomers】 (FKM) They exhibit excellent resistance to petroleum-based oils and fuels. They are durable against ultraviolet rays and atmospheric pollutants, making them suitable for outdoor use. Generally, they can be used at temperatures up to about 230°C. 【Fluoropolymers】 (PTFE) They demonstrate resistance to many substances, including acids, alkalis, solvents, fuels, and organic materials with a high oxygen index. Due to their very smooth and highly non-stick nature, other materials are less likely to adhere to them. This is widely known as the characteristic of PTFE (polytetrafluoroethylene), which is famous under the trademark name Teflon. Fluoropolymers have excellent resistance to high temperatures and can typically be used at temperatures up to 260°C. *By applying fluoropolymer processing to fluoroelastomers, the surface can gain the properties of fluoropolymers. For more details, please contact us.

■Difference Between Teflon and Fluoropolymer Teflon is a trademark of Chemours and is a brand name for fluoropolymers. Fluoropolymers include various types such as PTFE, FEP, PFA, and ETFE, but Teflon is a trademark for some of these. Teflon is a registered trademark of DuPont, represented by the 'R mark', while Chemours uses the 'TM mark'. Teflon-coated frying pans have popularized the term "Teflon coating" in society. Nowadays, the name Teflon is more well-known than the term fluoropolymer. Other chemical manufacturers also produce fluoropolymers, which are marketed under different product names. Industrial Teflon processing can be done at factories that have entered into licensing agreements with Chemours (DuPont). Yoshida SKT signed a contract with DuPont in January 1968 to become a Licensed Industrial Applicator (designated factory for industrial coatings).

List of 9 Representative Fluororesins ■PTFE Also known as polytetrafluoroethylene or tetrafluoroethylene, it is a white fluororesin with excellent sliding properties, non-stick characteristics, chemical resistance, and electrical properties. ■FEP A melt-processable perfluoropolymer developed after PTFE, it is a copolymer of TFE and hexafluoropropylene (HFP). Although its continuous use temperature is inferior to that of PTFE, it excels in moldability and non-stick properties. ■PFA A fluororesin developed to lower the melt viscosity while maintaining heat resistance equivalent to PTFE. It is a copolymer of tetrafluoroethylene (TFE) and perfluorovinyl ether (PFVE). ■ETFE A copolymer of TFE and ethylene, it is partially fluorinated. While it has excellent processability, its heat resistance and chemical resistance are lower compared to the above three types since it is not a perfluoropolymer.

Teflon coating is applied to frying pans and hot plates to prevent sticking. This explains the causes of peeling and how to address them. ■ Causes of Peeling Teflon is a brand name for fluoropolymer. Fluoropolymer is a type of plastic, making it softer and more prone to scratches compared to metal. The continuous use temperature is also lower, at up to 260°C, compared to metal. Therefore, simply scraping with a metal spatula or scrubbing hard with an abrasive sponge can cause scratches and lead to peeling. Additionally, extreme high-temperature environments, such as dry heating, can cause degradation or decomposition, so caution is necessary. Use a spatula made of resin, clean with a soft sponge, and if using a neutral detergent, it is important to rinse thoroughly. Residual surfactants can make the surface more prone to sticking. ■ Solutions In principle, Teflon coatings and fluoropolymer coatings cannot be partially repaired. Therefore, if it is a frying pan, we recommend replacing it. For industrial parts, reprocessing for peeling may be considered. Please contact us regarding the peeling methods and suitable base materials. Teflon-coated products can be used for a long time depending on how they are used. We recommend utilizing their features effectively.

Release properties refer to the characteristic of materials or products that allows them to be easily removed from molds or forming tools without sticking. This property is important in the manufacturing process and affects product quality and production efficiency. ■ Methods to Improve Release Properties By applying a release agent to the surface, a thin film is created between the mold and the product, preventing adhesion. Silicone and fluorine-based release agents provide excellent release properties for many materials. ■ Resin Coating Applying a resin coating to the surface exhibits non-stick properties, making it easier to remove the product. Fluororesin coatings are commonly used. ■ Metal Plating For example, chrome plating has high hardness and is less reactive with other substances, aiding in product removal. Fluororesin-containing types of plating also exhibit non-stick properties. ■ Surface Roughness Adjustment By designing the surface with fine uneven structures, the contact area is reduced, thereby decreasing adhesion. As mentioned above, there are various methods, but we will introduce surface treatment technologies and coatings that are particularly effective in enhancing release properties, reducing product defects, and improving productivity.

High-heat-resistant plastics are materials that possess characteristics suitable for use in high-temperature environments. These plastics generally have high melting points, excellent heat resistance, and chemical stability. ■ Polyimide (PI) Polyimide has very high heat resistance and can be used in environments up to 300°C. It is utilized in electronics, aerospace, and the automotive industry, particularly in situations where durability under high-temperature conditions and harsh environments is required. ■ Polyetheretherketone (PEEK) With a high heat resistance of 260°C, PEEK also offers chemical resistance and wear resistance, making it suitable for use in aerospace, medical, and energy industries. ■ Polyphenylene sulfide (PPS) PPS has high heat resistance and chemical resistance at 220°C and is used in the automotive industry, electronics, and industrial machinery. Fiber-reinforced types of PPS also have high wear resistance, making them suitable for mechanical parts. ■ Polytetrafluoroethylene (PTFE) PTFE has high heat resistance of 260°C, exhibits self-lubricating and non-stick properties, and has high chemical resistance, making it chemically stable. It is used in semiconductors, chemicals, medical applications, aerospace, and the automotive industry.

There are various types of fluorine coatings, even if we refer to them simply as such. Typical examples include PTFE, FEP, PFA, and ETFE. In practice, the heat resistance varies depending on the application, but the continuous use temperatures for fluororesins are defined. ■ Continuous Use Temperatures - PTFE: 260℃ - FEP: 200℃ - PFA: 260℃ - ETFE: 150℃ For example, when used as an anti-corrosion coating, the practical heat resistance will be at a much lower temperature. Additionally, when considering applications that involve friction or physical contact, further considerations are necessary. Fluorine coatings (fluororesin coatings) possess various properties such as non-stickiness, low friction, chemical resistance, electrical characteristics, and weather resistance, and it is essential to consider the type and thickness according to each application. *For more details, please click on "PDF Download" or feel free to contact us.

Teflon is a trademark of Chemours and refers to fluoropolymer. Fluoropolymers include types such as PTFE, PFA, and FEP, but currently, the use of fluoropolymers like PTFE, PFA, and FEP is not regulated in Japan. On the other hand, within the EU, regulatory proposals are being considered to minimize the emissions of PFAS. The following substances are also mentioned as targets: - Fluorinated surface treatment agents: water and oil repellents, release agents, fluoropolymer-containing coatings, etc. - Coatings: PTFE, PFA, FEP, ETFE, and other fluoropolymers (for applications such as corrosion lining, non-stick, lubrication, etc.) - Molding and processed products: PTFE, PFA, FEP, ETFE, and other fluoropolymers (such as lining sheets, fabric sheets, etc.) - Fluorinated surfactants, fluorinated oils, low molecular weight PTFE, fluorinated molding aids, etc. The regulatory proposals include fluoropolymers, which are considered to be extremely stable and pose no toxicological or environmental concerns.

The difference between fluoropolymer and Teflon is the difference between a general name and a trademark. Fluoropolymers include various types such as PTFE, FEP, PFA, and ETFE. Teflon is a trademark of Chemours and is a brand name for some fluoropolymers. Therefore, even if they are referred to differently, such as fluoropolymer coating or Teflon processing, they may refer to the same coating. PTFE was discovered in 1938 by Dr. Plunkett of DuPont in the United States and was later marketed as Teflon PTFE. It later became famous for Teflon coating on frying pans, and the name Teflon became widely known. Currently, the Teflon trademark can only be used in factories that have entered into a licensing agreement with Chemours. Yoshida SKT entered into a contract with DuPont in January 1968 as a Licensed Industrial Applicator.

There are various types of resin for fluoropolymer coatings depending on the application environment. At Yoshida SKT, we specify materials and processing based on the product number. 'STP-HS' is a type of fluoropolymer coating designed to reduce contact area and is one of the 'Super TP Coating Hemisphere Graphics'. Super TP Coating uniquely forms a convex surface using only fluoropolymer, characterized by excellent release properties and slip resistance against adhesives. For more details, please download the materials or contact us.

■Customer's Issue In vacuum forming of films, the formed film was difficult to detach from the mold, resulting in release failure. ■Background / Conditions for Choosing Treatment The cause was uneven heating and poor air release due to inadequate adhesion between the mold and the film. ■Adopted Coating Super TP Coating ■Achieved Effects The Super TP Coating forms a smooth convex surface with fluororesin. The convex surface of the coating created an appropriate gap between the mold and the film, improving air release and resolving the issue of uneven heating, resulting in better release properties.

Solving the challenges of fluoropolymer coatings! Conventional fluoropolymer coatings required a thickness of 20-50μm to maintain good appearance and performance. However, the thick film affected the dimensional stability of the substrate. With its unique technology, 10under has achieved processing with a thin film of about 10μm. ■Features Processable with a film thickness of less than half of conventional coatings! (10μm) Reduces dimensional changes Suppresses transparency even with a thin film, achieving a beautiful appearance Available in two types: PFA and FEP, in two colors: black and green *For more details, please download the materials or contact us.

The 10under thin film fluoropolymer coating possesses non-stick properties equivalent to standard fluoropolymer coatings while being processable at a thickness of approximately 10μm. As a result, the dimensional changes due to film thickness are reduced compared to the standard type. Additionally, despite being a thin film, it minimizes transparency and prevents aesthetic defects. When compared to other fluoropolymer coating products, it is generally considered that a thickness of at least 20-50μm is required to maintain good appearance and performance. Therefore, when requesting processing with a thin film like 10under, it was common to propose a "modified type" fluoropolymer coating; however, there are challenges where the modified type may not exhibit the necessary functions. 10under addresses such challenges and is capable of demonstrating high performance while being a thin film. For specific comparisons and detailed information, please check the link.

10under is a fluororesin coating that enables thin film processing at a film thickness of 10μm, which was previously difficult to achieve. Traditional fluororesin coatings required a thickness of about 20-50μm, but 10under can be processed with a thin film of about 10μm. **Benefits of 10UNDER** - Reduction of dimensional changes The thinning of the film can reduce dimensional changes in the substrate. - Suppression of transparency Despite being a thin film, it suppresses transparency and prevents appearance defects. - Minimization of thin plate deformation It can minimize the deformation of thin plate substrates. If you want the same non-stick properties as standard fluororesin coatings while suppressing transparency and preventing appearance defects, and if you want to minimize the deformation of thin plate substrates, please consider 10UNDER. You can check specific comparisons and detailed information via the link.

■Issue We want to prevent the adhesion of resin films in a high-temperature environment of up to 180°C. A surface treatment that can accommodate both polypropylene bags and aluminum vapor-deposited bags is necessary. The current treatment has a short lifespan and requires frequent replacements. ■Background The heater block is an important component in the sealing process of packaging bags. When heat is applied to bond the resin film, there is a problem where the resin from the film easily adheres to the surface of the block. The customer tried surface treatments from other companies but did not achieve sufficient results, making the realization of stable non-stick properties and long lifespan urgent. ■Adopted Treatment We developed our unique "TP Coating" and applied it to the surface of the heater block. ■Features - Excellent release properties that prevent resin adhesion - Stable performance even in high-temperature environments - Selection process for the treatment ■Effects - Achieved a lifespan of about 4 months with an operating frequency of 10 times per minute - Reduced cleaning frequency and operational losses by maintaining non-stick properties - Improved operational efficiency of the production line with stable performance under high temperatures For more details, please refer to the catalog or contact us directly.
