Among PFAS, PTFE (fluoropolymer) is a substance that has different properties from PFOS, PFOA, and PFHxS, which are regulated under international treaties (the POPs treaty). Unlike these substances, PTFE is considered to have no harmful effects unless used at significantly high temperatures. However, there is currently a proposal being considered within the EU to regulate a comprehensive range of PFAS, including PTFE. If this regulatory proposal is adopted, it could lead to international regulatory trends beyond the EU, so it is necessary to keep an eye on developments. If regulations on fluoropolymers become a reality, the impact on the manufacturing industry could be immense, forcing companies to seek alternatives. Since there is no technology that can completely replace the excellent functions of fluoropolymers, the response will be extremely challenging. Yoshida SKT offers both fluoropolymer coatings (Teflon coatings) and non-fluoropolymer coatings, providing proposals tailored to customer needs. For more details, please check the link.

■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.*

This manufacturer was facing a problem in the manufacturing process of pain-relieving and anti-inflammatory adhesive patches (wet compresses), where products were sticking to the transport equipment, leading to line stoppages and product defects. The product consists of a three-layer structure, with an effective ingredient-containing paste layered on a supporting substrate and a release film. This paste was coming into contact with the transport guide, causing adhesion, which resulted in line stoppages and product bending defects. In response, we proposed the "MRS Coating," which excels in non-adhesiveness. This coating is effective even against adhesives like those found in duct tape. As a result of evaluations conducted with actual products and samples, it was confirmed that there was no sticking, and it was adopted for use in the actual machines. As a result, the sticking issues were eliminated, leading to a reduction in defective products, an improvement in the good product rate, and a decrease in maintenance time associated with line stoppages. Are you facing similar issues? The "MRS Coating" may contribute to improving the efficiency of your manufacturing line. Please feel free to contact us for more information.

■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.*

■Corrosion and Insulation of Stainless Steel Stainless steel is known for its resistance to rust, but it can experience galvanic corrosion between dissimilar metals. By coating it with a highly insulating resin to eliminate electrical contact, galvanic corrosion can be prevented. ■Highly Insulating Resins In general, plastics (resins) do not conduct electricity. Among them, resins such as fluororesin and polyimide are particularly excellent in electrical insulation and heat resistance, making them suitable for various applications. ■Cautions for Insulating Surface Treatments By insulating the surface of stainless steel with coatings like fluororesin, it is possible to maintain a state where electricity does not flow through the stainless steel surface. However, such coatings may require high-temperature curing and must be free of pinholes. Therefore, considerations regarding the design of the base material (component) and film thickness are necessary, and it is appropriate to consult a specialized contractor. *For information on the electrical properties of fluororesins, please click "PDF Download" or feel free to contact us. If you are considering an insulating coating for stainless steel, please do not hesitate to contact Yoshida SKT.

For preventing the sticking of sticky adhesive substances, which does not work well with Teflon coatings or fluororesin coatings, the following general measures have been taken, but there are limitations. ≫ Silicone release agents These are spray-type agents that can be easily applied by on-site workers and are familiar as release agents for resin molding. → However, they lack durability in their effectiveness, requiring frequent reapplication, and when wiped off with solvents for cleaning, the release agent is also removed. ≫ Surface roughening (physically reducing contact area) By making the surface of the components uneven, it becomes less likely for things to stick. There are many examples where combining this with Teflon coatings enhances effectiveness. → However, there are concerns about the risk of defective products due to the uneven shape being transferred to the product, and the difficulty of wiping or cleaning during maintenance due to the roughness. Our company has further evolved a smooth silicone coating that is effective against sticky adhesive substances and allows for solvent cleaning, tailored to the "troubles" faced on-site. We are currently offering a "feel the effect kit" for free! The "experience kit" can be requested from the official Yoshida SKT website.

■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.

Problems I wanted to solve and things I wanted to achieve There was an issue with epoxy adhesives adhering to the mold. The silicone-based release agent used had good release properties, but it easily transferred to the molded products, causing adhesion failures in subsequent bonding processes. Background/Conditions for Choosing Treatment What was needed was mold release without silicone. Additionally, materials that could withstand the pressure of molding and allow for low-temperature processing applicable to aluminum molds, which are prone to thermal deformation, were required. Achieved Effects Among the Bi-Coat series, "Bi-Coat Exceed NYK-2000E-C" was chosen. This is a fluorine-based coating that does not cause silicone transfer issues and allows for low-temperature processing, making it safe to use on aluminum molds. With this coating, the use of silicone-based release agents became unnecessary, achieving a silicone-free environment. Mold release troubles were resolved, and the quality and productivity of the products improved. **Features of Bi-Coat NYK-2000E-C** - Silicone-free - Low-temperature processing available - Prevents adhesive adhesion to molds For more detailed inquiries about Bi-Coat, please contact Yoshida SKT!
