Sustained release properties surpassing fluororesin! The release effect of resin-welded plates has improved threefold.

The welding process for containers and lids necessary in the production line of lead-acid batteries. We will introduce examples of coatings that suppress resin adhesion to the welding mold and allow for long-term use!

■Concerns Lead-acid batteries, widely used in automobiles and commercial power sources. In the production process, after filling a resin box with electrodes and other components, the container and lid are welded to seal them. The heating plates used for welding are made of aluminum and are heated to over 200°C, but due to the occurrence of melted resin and stringing, a fluororesin (PTFE) coating was applied. ■Background In a production line that operates at temperatures above 200°C and produces several thousand shots a day, the coating on the heating plates peels off in less than a week. Reprocessing the coating has caused issues such as the hassle of changing setups and damage to molds, leading to decreased production efficiency. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects Therefore, we proposed the newly developed "CHC-1111CR," which has equivalent release properties to fluororesin coatings and high hardness of the coating film during heating, making it resistant to peeling and wear. Testing on the actual line showed no stringing of the resin and no peeling of the coating, allowing for use in tens of thousands of shots and achieving a lifespan approximately three times that of conventional coatings. *For more details, please refer to the PDF document.*

Fluororesin Coating: "What is 'Blasting' in Surface Preparation?"

Surface treatment for firmly adhering a non-stick "fluoropolymer coating" to the substrate. This explains "blasting."

■What is blasting? Blasting is a surface treatment method that involves spraying blast materials (various abrasive particles) onto the surface of a product using compressed air or similar means to remove rust and dirt from the substrate surface. The particles that collide with the surface act as "impact" or "cutting." Although the energy of a single blast particle is minimal, the continuous bombardment of countless particles results in a significant effect on the surface. ■Blasting as a pre-treatment In addition to cleaning the surface, blasting increases the surface area through roughening, which generates an anchor effect that greatly enhances adhesion during coating processes. Therefore, it is extremely effective not only for fluoropolymer coatings but also as a pre-treatment for processes such as thermal spraying and plating. Additionally, blasting can improve the wettability of liquids. To fully realize the performance of fluoropolymer coatings, pre-treatment is a crucial process. At Yoshida SKT, we select blast materials and treatment methods suitable for coatings and substrates to process fluoropolymer coatings. *For more details, please check the link below or feel free to contact us.

Fluororesin Coating: "What is the 'Air Baking' in the Degreasing Process?"

A degreasing process to ensure strong adhesion of the non-stick "fluororesin coating" to the substrate. This explains "pre-baking."

■ What is the degreasing process? It is the process of removing oils, fats, and dirt that are attached to the surface to be coated. ■ Issues arising from insufficient degreasing It can lead to problems such as the coating material repelling, poor adhesion of the paint film, and the occurrence of appearance defects like stains. ■ Types of degreasing methods - Air roasting - Solvent cleaning ■ Air roasting process The substrate is heated in a roasting furnace to a temperature above the coating processing temperature, allowing oils and other substances to be oxidized and burned off. Typically, roasting is performed for several hours at temperatures exceeding 400°C. ■ Advantages of air roasting - No toxic gases are generated during the decomposition of oils, which are broken down into water and carbon dioxide. - It can completely decompose all organic components that could cause problems during the coating firing process. - It can accommodate large products as long as they fit into the roasting furnace. Fluoropolymer coatings, which excel in non-stick properties, adhere firmly to the substrate and perform effectively when a proper degreasing process (surface preparation) is carried out. * For an overview of the fluoropolymer coating process, please download the PDF or feel free to consult us.

Fluororesin Coating: "What is the Lubricity of PTFE?"

[Presentation of Information] What makes fluoropolymer excellent in lubrication? We will introduce the characteristics of fluoropolymer PTFE, focusing on its lubrication and low friction properties.

■Types of Lubrication Lubrication can be broadly divided into liquid lubrication using liquids and solid lubrication using solids. A representative example of liquid lubrication is lubrication with oil. On the other hand, lubrication with fluororesin falls under the category of solid lubrication. ■Characteristics of Solid Lubrication Solid lubrication is used in cases where liquids cannot be used or when liquids evaporate or detach in a vacuum. For example, when sliding products, solid lubrication is useful in cases where liquid lubricants would dirty the products. ■Lubricity and Low Friction of Fluororesin (PTFE) Fluororesin has a low coefficient of friction and is used as a solid lubricant. Fluororesin 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 a very small polarity due to their symmetrical 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 Fluororesin PTFE → For more details, please check the basic information section.

Coating that controls the contact area - "Non-stick coating"

Prevention of sticking for sticky materials such as molten resin plastic, labels, adhesive tape, and raw rubber. This is a coating that exhibits excellent non-stick properties.

We have prepared a series that exhibits excellent non-stick properties, particularly against sticky substances, molten resins, adhesives, and adhesive tapes. ■ Series Composition - Super TP/TP Series (composed entirely of fluororesin) - Super CTT Series (composed of surface treatment + silicone-based materials) - Super Alloy Coating (composed of fluorine type and silicone type) ■ Super TP/TP Series (composed entirely of fluororesin) This series can be used in silicone-free environments. Additionally, since it is made entirely of fluororesin, there is no concern about transfer or contamination from silicone oils. Improved slip properties can also be expected due to reduced contact area. ■ Super CTT Series (convex surface + silicone rubber-based) Due to the use of silicone, this series exhibits excellent non-stick properties and low tackiness. Consideration for transfer to the counterpart material is necessary during use. ■ Super Alloy Coating A convex release coating that balances flexibility and high hardness. Surface treatment of HV600 can also be processed onto resins and sponge rubber. *For more details, please download the PDF or feel free to contact us.

Teflon Coating: "What is the method to enhance corrosion resistance with Teflon resin?"

What is the method to protect metal from corrosion with Teflon coating? Can corrosion be prevented by just preventing one single factor?

■Corrosion of Metals Corrosion refers to a state in which the appearance or function of an object is impaired due to chemical or biological actions. Iron is generally cited as a metal material that is prone to corrosion. These metals can develop rust and corrosion as a result of factors that cause corrosion, such as oxygen, sulfur, nitrogen, and water vapor in the atmosphere, along with the inherent properties of the metal, impurities, and electrochemical reactions. ■Three Elements of Corrosion - The flow of electricity - The presence of water - The presence of oxidants By preventing any one of these elements through coating, metal corrosion can be prevented. ■Prevention of Metal Corrosion by Teflon Coating Teflon fluoropolymer is widely used as a corrosion-resistant material due to its exceptional chemical resistance among resins. This is not only because of its superior chemical resistance but also due to its properties such as heat resistance, cold resistance, weather resistance, non-stick properties, purity, low friction, and processability. It can be said that advancements in both the development of Teflon resin varieties and processing technologies have allowed for the selection of materials and shapes suitable for various applications. *For more details on Teflon coating, please refer to the catalog or contact us.*

Fluororesin Coating: "Differences in Color and Selection Method"

We will introduce the differences in color and how to choose coatings that encapsulate fluororesin, such as fluorine processing and fluororesin coatings.

■What color is fluoropolymer? The fluoropolymer coating commonly seen on household frying pans is often a dark color, but PTFE, which is frequently used for frying pan coatings, appears milky white under sunlight. ■Colors of fluoropolymer coatings Fluoropolymer coatings come in various colors, including green and gray, in addition to dark colors. This is because the coating materials are colored to enhance aesthetics and allow for differentiation based on purpose. ■Differences by color The differences in color of fluoropolymer coatings are not closely related to the type or characteristics of the resin. For example, green does not necessarily indicate PFA, nor does black indicate PTFE. Since fluoropolymer coatings are functional films, it is essential to choose them appropriately based on their intended use and environment. In such cases, it is important to consult a reliable processing company rather than selecting based solely on color. ■Fluoropolymer coatings for specific applications Fluoropolymer coatings demonstrate various functions depending on the type of resin, film thickness, and processing methods, across different applications and environments. It is crucial to select the appropriate coating based on the intended use, such as for non-stick purposes or corrosion resistance.

[Surface Treatment Solution Case] Achieving both high-temperature release and long lifespan with thermal welding type!

Improvement of the thermal fusion process of the filter case through surface treatment. Achieving reduced thread pulling and long lifespan with heat-resistant fluorine coating!

■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.

Solving the challenges of silicone (silicon) release agents with silicone coatings.

We will solve the challenges of silicone (silicon) release agents with silicone coatings!

■What is a release agent? In the industrial field, a release agent is known as a substance applied to improve the separation of molded products from molds. In a broader sense, substances like the flour used to prevent soba noodles from sticking during preparation can also be referred to as release agents. ■Silicone (Silicon) Release Agents Release agents used for molds include silicone and fluorine, depending on the material and conditions. In addition to facilitating mold release, release agents must also have properties that make them resistant to degradation from heat during molding and minimize contamination of the mold. Silicone has high heat resistance and is less likely to degrade with repeated heating during molding. Additionally, due to its low surface tension, it has good wettability on molds, allowing it to reach every corner of the shape, which is one reason it is commonly used as a release agent. ■Release Agents and Coatings In addition to release agents, coatings can also provide release effects. While release agents are an easy means of achieving mold release, they can impose burdens on the working environment, complicate mold cleaning, and lead to variations in the amount applied by workers, potentially negatively affecting the final product. In such cases, release coatings may offer solutions to these challenges. ▼For more details, please see here.

Fluororesin Coating: "What is the Water and Oil Repellency of Fluororesin?"

What are the typical characteristics of Teflon fluoropolymer coating, specifically "water repellency and oil repellency"? Let me introduce the mechanism.

■What is the "Water Repellency" of Fluororesin? "Water/Oil Repellency" refers to the property of a material's surface to repel water and oil. A well-known example that illustrates this property is the lotus leaf. The lotus leaf utilizes this water repellency to keep itself clean and less prone to wetting, allowing for smooth photosynthesis. Teflon fluororesin also possesses this "water/oil repellency." For instance, even if a liquid tends to spread on a material, applying a Teflon fluororesin coating to the surface can impart water/oil repellency, causing the liquid to bead up and reducing its tendency to spread. You can find detailed information in the PDF document below. ---------------------------------------- 1. What is water/oil repellency? 2. Reasons why Teflon fluororesin excels in water/oil repellency ~Surface Free Energy~ 2-1. What is surface free energy? 2-2. The relationship between water repellency and surface free energy 3.

[Surface Treatment Case] Surface treatment that streamlines the manufacturing process of lithium-ion batteries.

Prevention of adhesion of adhesive tape used in lithium-ion battery manufacturing. Achieving both extended maintenance periods and prevention of line stoppages with surface treatment suitable for cutting tools.

We would like to introduce a case study on the improvement of cutting equipment for insulation tape used in the manufacturing of lithium-ion batteries. ■ Key Issues - Problems arose when adhesive material adhered to the cutting blade, causing the line to stop. - The blade type is a shear type with two blades, similar to scissors. - To prevent line stoppages, frequent cleaning was required, which decreased production efficiency. ■ Selection Process - We wanted to perform surface treatment using commercially available blades. - It was necessary to select a surface treatment that does not change the cutting performance. - A long-lasting surface treatment was needed to prevent line stoppages and reduce cleaning frequency. ■ Effects of Coating - It was possible to strip the original surface treatment of commercially available blades for processing. - Adhesive adhesion was eliminated, reducing the labor required for cleaning. - Preventing line stoppages and the need for line stoppages for cleaning became unnecessary. Non-stick coating on blades contributes to improved productivity, cost reduction, and enhanced safety. We also have a collection of case studies and trial sets for improvements in the cutting process. ▽ Click here to apply for the collection of cutting process improvement case studies and trial sets ▽

Teflon Coating: "What is the difference between frying pan use and industrial use?"

I will explain the difference between Teflon coating commonly seen on frying pans and the Teflon coating processed for industrial use.

◆Differences Between Frying Pans and Industrial Teflon Coatings◆ Teflon processing for frying pans typically involves products made with PTFE at a thickness of about 20 to 50 micrometers. PTFE is a representative fluororesin and is the first resin developed. Formally, "Teflon" is a registered trademark of the fluororesin by DuPont in the United States, while the general term is fluororesin processing (coating). PTFE not only excels in non-stick and water-repellent properties but also has good heat resistance, making it suitable for frying pans. On the other hand, industrial Teflon coatings not only have the non-stick properties like frying pans but are also used for various applications such as improving slip, protecting substrates from chemicals, and enhancing insulation properties. Therefore, the types of resins used include not only PTFE but also PFA and FEP. Our company can process PTFE coatings, but we also offer Teflon coatings using various materials and technologies. *Note: "Teflon" is currently a trademark of Chemours. Our company has a licensing agreement with Chemours and is capable of processing Teflon coatings in our own factory.

Introduction of the development product: Thin film fluororesin coating 10under.

This is a groundbreaking fluororesin coating that has made it possible to process thin films with a thickness of 10 μm, which was previously considered difficult to process.

■Development Background of Thin Film Fluororesin Coating "10under" Fluororesin coatings are sometimes requested to be processed in thin films of around 10μm when dimensional stability of the substrate is a priority. However, in the case of standard fluororesin coatings, a thickness of at least 20-50μm has been required to maintain good appearance and performance. Even so, when requests for thin film processing arise, we sometimes propose a "modified type" of fluororesin coating with a different coating structure. However, there were challenges with the modified type not being able to deliver the necessary functions. Yoshida SKT has worked on development to solve these challenges, resulting in the creation of the "Thin Film Fluororesin Coating '10under.'" ■Features of 10under - Non-stick properties equivalent to standard fluororesin coatings - Capable of processing thin films of around 10μm, reducing dimensional changes - While being a thin film, it suppresses transparency *For more details, please download the materials or contact us.*

Fluororesin Coating 'HBA-838'

Explanation of Yoshida SKT's fluororesin coating 'HBA-838'.

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.

List of Mold Release Coatings - Surface Treatments Excellent in Release Properties and Prevention of Eye Goo

When you want to reduce adhesion for mold release applications, it is effective in simplifying mold cleaning and stabilizing product quality!

In mold forming, to stabilize product quality, it is important to improve release properties and prevent mold contamination. Measures such as PVD coating, DLC coating, and chrome plating are being implemented, but depending on the molding conditions, issues can arise where parts of the product stick, or eye residue becomes a cause of product defects. We would like to introduce coatings that have a proven track record of improving the release properties of molds. 【Selected Coatings (Partial)】 ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Release properties, eye residue prevention - MRS Coating ■ Resin release at high temperatures - FSR Coating ■ Non-stick and slip properties - Teflon / Fluororesin Coating ■ Release properties, precision (precision parts, precision molds) - Nano Process *For more details, please refer to the PDF document or feel free to contact us.

What is a method to reduce the release resistance of the ejector pin? Countermeasures through surface treatment.

Solve ejector pin troubles with surface treatment technology! Easy demolding even with soft resins that are less likely to stick.

■What is an ejector pin? Also known as a push-out pin, it is a pin incorporated into a mold to push out and remove molded products from the mold. Ejector pins are used in most injection molding molds and come in various shapes, materials, and sizes. It is important to choose the appropriate pin for demolding based on combinations of shapes such as round pins, square pins, and middle flange pins, as well as materials like SKD-61 and SKH-51. ■Methods to reduce the demolding resistance of ejector pins To reduce the demolding resistance of ejector pins, methods include mold design, pin arrangement and shape selection, and reviewing molding conditions. However, in cases of materials that tend to stick or soft resins, sticking can lead to demolding failures. In such cases, it is necessary to consider utilizing surface treatment technologies. ■Surface treatments to improve the demoldability of ejector pins Ejector pins need to protrude from the mold, so they require not only demoldability but also wear resistance and dimensional stability. Yoshida SKT's Bicoat has a proven track record of achieving smooth demolding when applied to ejector pins. For more details on Bicoat, please download the catalog and check.

Advantages and disadvantages of re-coating a non-stick frying pan.

A professional introduces the advantages and disadvantages of reprocessing the non-stick coating and Teflon coating of household frying pans.

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.
