Wear refers to the process in which one or both of two objects in contact and moving against each other become abraded. There are two main types of wear that can occur in manufacturing environments. One is "rough wear," which occurs when surfaces are abraded and eroded due to contact with rough surfaces or particulate matter. The other is "thrust wear," which happens when surfaces adhere due to frictional heat and are worn away by the opposing material. The appropriate surface treatment varies depending on the type of wear. [Selected Surface Treatments] ■ Wear Resistance (Rough Wear) - Urethane Coating ■ Wear Resistance (Thrust Wear) - Bi-Coat *For more details, please refer to the PDF document or feel free to contact us.

■Consultation In the production process of cartridge filters, the adhesion of resin to the heat welding plate used for welding the products has been a problem. The products are completed by thermally welding polypropylene containers and lids, but PP resin tends to cause stringing and adhesion to the welding jigs, negatively affecting the product's airtightness, appearance, and production efficiency. Therefore, the heat welding plates required not only excellent release properties but also heat resistance and thermal durability. ■Background of Coating Selection In the prototype, in addition to the standard fluororesin coating, we proposed a contact area-reducing fluorine coating "TP-855." Since the welding process involved relatively low pressure, the release properties improved, making stringing and adhesion less likely. Additionally, it was used for a relatively long lifespan. ■History and Effects of Coating To further extend the lifespan of the release effect, we considered hybridizing the high thermal hardness CHC series with the contact area-reducing coating. Aiming for even longer lifespan, we proposed "CHC-1311," which balances thermal hardness and contact area reduction. Currently, there is no metal exposure due to wear, and it is being used effectively. If you are facing issues in the heat welding process, please consult Yoshida SKT.

In fluororesin sheet lining processing, there are two methods: "adhesive lining," where sheets made of PTFE or PFA are processed to allow one side to be bonded using a special method and then adhered to the substrate with adhesive, and "loose lining," a processing method like lining pipes where the liner is not bonded to the substrate. Sheet lining can process thicker linings compared to many other fluororesin lining methods. This results in excellent corrosion resistance among various fluororesin linings. On the other hand, the adhesion strength with the substrate depends on the adhesive's bonding power, so it generally does not accommodate use in negative pressure environments. Negative pressure applications can be addressed with other methods such as baked lining or roto-lining. *You can download a document summarizing the details of the lining.

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.

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.

■Features of PTFE Coating PTFE has the characteristic of having extremely low resistance due to friction compared to other resins. By processing PTFE coating, the static friction coefficient of the substrate surface can be reduced, allowing two objects in contact to be moved with a small force. ■Low Friction of PTFE Coating - Due to the strong atomic bonds within PTFE molecules, the intermolecular forces of the contacting material with PTFE molecules are reduced. - Friction (sliding) causes PTFE molecules to adhere slightly to the contacting material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with few irregularities. - The orientation of PTFE molecules makes it easier to alleviate friction resistance. It is believed that the molecular structure influences the low friction coefficient of PTFE coating. *For more details on fluoropolymer coatings, including PTFE coatings, please download the catalog or contact us.*

"Die biting" refers to the phenomenon where resin sticks to or gets caught in the mold, causing scratches or defects in the molded products. This can occur when resin adheres to the mold's gates or flash surfaces, or when the mold patterns do not transfer to the surface of the molded products. When die biting occurs, it can lead to a decline in the appearance quality and dimensional accuracy of the molded products, potentially worsening product quality. Additionally, it may necessitate repairs or maintenance of the mold, which can adversely affect productivity. **Methods to Prevent Die Biting:** Surface Treatment: Properly treating the surface of the mold makes it less likely for resin to stick to it. Improvement of Gate Design: By considering the flowability of the resin and the balance of forces during withdrawal, a gate design can be implemented that prevents die biting. Optimization of Molding Conditions: Optimizing molding conditions can make it less likely for resin to stick to the mold. For example, it is important to appropriately set molding conditions such as molding temperature, injection speed, injection pressure, and holding pressure. Mold Maintenance: Proper maintenance can prevent the occurrence of die biting. Effective measures include cleaning the surface, correcting gates and flash surfaces, and using air blow.

■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!"

■What is Friction Friction occurs when two objects come into contact and move against each other, generating resistance on their surfaces. The force that arises during this process, which acts as a hindrance, is called frictional force. There are two types of friction: static friction and kinetic friction. The resistance force that acts until the objects start moving is called static friction, while the resistance force that acts after they start moving is called kinetic friction. ■Characteristics of PTFE Fluoropolymer PTFE has an exceptionally low resistance due to friction compared to other resins. The static friction coefficient of PTFE is about 0.04, allowing it to move two objects in contact with a small force. ■Low Friction Properties of Fluoropolymer (PTFE) Fluoropolymer (PTFE) has a low friction coefficient and is also used as a solid lubricant. PTFE has a structure where fluorine atoms tightly surround carbon atoms. The free energy of the fluorine atoms on the molecular surface is low, and the molecules exhibit extremely low polarity in their structural characteristics. This molecular structure is believed to influence the low friction coefficient of PTFE. ■Reasons for the Low Friction Coefficient of Fluoropolymer PTFE → Please check the basic information section for more details.

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.

We wanted to address the impact of release agent spraying on human health and the deterioration of the environment! ■ Background for selecting surface treatment - Since mass-produced items require several hours for a single molding, we wanted to reduce the effort of reprocessing surface treatments due to the large number of molds. - We wanted to avoid contamination of products due to wear or peeling of the surface treatment. - We also wanted to maintain the dimensional accuracy of the molds. ■ Effects achieved through surface treatment - We adopted a surface treatment that maintains dimensional accuracy and is resistant to peeling and wear. - By using it in conjunction with release agents, we successfully extended the lifespan of the surface treatment and reduced the amount of release agent used. ■ Currently, we are offering a trial set and a collection of case studies for improvements in the molding process! The case study collection can be viewed by downloading the PDF. You can apply for the sample book through the related links.

Aluminum is widely used in various applications as packaging machines and transport components due to its lightweight and ease of processing. We introduce a surface treatment that addresses challenges that could not be solved even with anodizing or fluororesin processing. ■ Issues arising in packaging machines and manufacturing lines In packaging lines for food and pharmaceuticals, aluminum guides are used to transport products. Even with anodizing or fluorine processing, there can be issues such as line jams or surface wear. ■ Key points for problem-solving In such cases, by adopting 'Bicoat,' which combines the hard coating of HV700-900 with the lubricating properties of fluororesin, we achieve both wear resistance and smooth sliding, thereby resolving issues related to the smooth transport of products and surface wear. *For more details on 'Bicoat(R)' introduced in the examples, please download the materials and check.

We would like to introduce a case study that resolved film adhesion issues that could not be solved with fluororesin coating on fusion molds. ■Consultation Details In the fusion process where a film is used to cover a container, the fusion mold is heated to over 100°C, causing the surface of the film to melt. Initially, fluororesin coating was applied to the mold to prevent film adhesion. ■Background of Selection Due to the material of the film and the melting temperature, film adhesion to the fusion mold was causing product defects. The mold has small holes for vacuuming the film, and there were limitations on options due to conditions such as not blocking these holes. ■Coating Adopted 'TP Coating' ■Adoption Background and Effects To meet the customer's usage conditions, we proposed a coating that has better release properties than the current coating and does not block the mold's holes, reducing the contact area. The customer adopted the "TP Coating," which has excellent release properties and does not affect vacuuming. *For more details, please refer to the materials or contact us directly.

Stainless steel is used in situations where products are packaged or transported. We introduce surface treatments that lead to solutions for challenges that could not be resolved by polishing the surface or embossing. ■Problems Occurring in Packaging Machines and Production Lines In packaging lines for food and pharmaceuticals, products are transported using stainless steel guides. Even if stainless steel is polished with a buff or embossed to facilitate product flow, there can be occurrences of line jams. ■Key Points for Problem Solving When using polishing materials for transport guides, if the surface becomes even slightly less slippery during high-speed and high-volume transport, products can jam, causing the equipment to stop. The slippery "fluororesin coating" allows products to flow at high speeds, but there are concerns about foreign matter contamination due to wear particles from the coating. In such cases, by adopting 'Bicoat,' which combines the hard coating of HV700-900 with the lubricating properties of fluororesin, we can achieve both wear resistance and slip properties, thus solving the issues of smooth product transport and surface treatment wear. *For product information on 'Bicoat(R),' please click on "PDF Download" or feel free to contact us.

We will introduce a case study on solving the problem of epoxy adhesive sticking out from electronic components. ■Consultation Details The consultation was regarding a problem where adhesive that protruded from the components was sticking to the plate used for transporting the electronic parts. ■Background for Selection The process included a curing step at 150°C, and precision of the transport plate was also required. ■Coating Adopted 'Nano Process TLS-200' ■Reason for Adoption and Effects We proposed two types of coatings with good surface treatment precision that do not allow epoxy adhesive to stick. After testing, they chose to adopt the Nano Process. *For more details, please refer to the materials or contact us directly.*

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.

The Nano Process "TLS Series" has achieved a non-adhesive property that allows sticky substances, like duct tape, to peel off easily with a thin film of less than 1μm. Thanks to the surface treatment technology of 1μm thin films, it can maintain optical properties with minimal dimensional changes, making it possible to process "precision parts" and in fields that require high dimensional and surface accuracy, where non-adhesive surface treatments like fluororesin coatings have been difficult. <Examples of Applications> - Non-adhesiveness for products with high adhesive strength, like duct tape - Prevention of adhesion for sealing materials in electronic components - Prevention of adhesion for hot melt adhesives - Prevention of adhesion for silicone adhesives, etc. Additionally, the Nano Process has been renewed with three other new functions, each with different features and applications. 【Features of the Series】 ■ TC-10S Excellent precision, visible light transmittance, water repellency, and oil repellency ■ NCFPC Series Excellent liquid slip properties for water and oil ■ HP Series Excellent hydrophilicity We are currently offering a technical document summarizing the details of the series.
