■The "non-stick property" of fluoropolymer… Non-stick property refers to the characteristic of being easy to release and not adhere, or to adhere less, even to strongly adhesive substances. For example, fluoropolymers have excellent water and oil repellency, a large contact angle, and due to their molecular structure, they possess a property of being difficult to wet. The measure of wettability, "critical surface tension (γc)," is extremely low for fluoropolymers, making it easy for liquids to be repelled and difficult to wet. Coatings that utilize such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Reference data on non-stick properties】 ■Surface free energy of solids (dyn/cm) PTFE…18.5 PFA…17.8 FEP…17.8 ETFE…22.1 Fluoropolymers have low surface treatment free energy and possess properties that make them difficult to bond with various liquids and solids. By coating with fluoropolymer, dirt is less likely to stick and becomes easier to clean. *For detailed information on fluoropolymer coatings and non-stick properties, please download the PDF or contact us.

PTFE (polytetrafluoroethylene) is the most widely used fluoropolymer and is also known by the brand name "Teflon." It is a material with properties such as non-stickiness, low friction, chemical resistance, weather resistance, excellent electrical characteristics, and high heat resistance (maximum operating temperature of 260°C). In response to trends in PFAS regulation, we are advancing the development of coatings using alternatives such as silicone and other engineering plastics as substitutes for PTFE (fluoropolymer). By appropriately adopting these alternatives according to their applications, it is expected that desirable functions can be achieved. 【Characteristics】 ■ Alternative technologies utilizing super engineering plastics such as silicone, PEEK, and PI ■ Non-fluorinated coatings optimized for specific applications ■ Functionality tailored to applications, such as release properties, non-stickiness, and chemical resistance 【Non-Fluorinated Coating Product Lineup】 Yoshida SKT continues to develop products in collaboration with customers, offering new non-fluorinated coating products as options to address next-generation challenges.

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 is Thick Film Fluororesin Coating Technology? Fluororesin, which has excellent chemical resistance, is chemically stable and is not affected by most acids, alkalis, or other chemical agents, nor do ions dissolve and leak out. On the other hand, if the coating film is thin or if there are pinholes, it can negatively impact the protection of the substrate from chemical solutions and the leaching of impurities. With thick film coating technology, it is now possible to achieve pinhole-free thick film processing on can bodies and substrates where lining and molding are not feasible, providing protection from corrosive liquids and gases such as acids and alkalis, as well as preventing the leaching of metal ions. *For more detailed information on thick film processing of fluororesin coatings and corrosion resistance, please refer to the link below.

The coatings in the GLC series are designed to suit the heat resistance and characteristics of various types of rubber. The coating processing temperatures are selected to not exceed the heat resistance of the rubber materials. Therefore, it is possible to apply the coating without compromising the physical properties of the rubber. Additionally, due to the nature of rubber, it can stretch and shrink with even small forces.

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.

"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.*

"Non-stick" can be rephrased as non-adhesive. By processing a non-stick coating, it becomes easier to release from strongly adhesive substances, resulting in surfaces that either do not adhere or are difficult to adhere to. Such properties can be achieved through fluoropolymer coatings or silicone coatings. Not only for household frying pans but also for improving the release properties and reducing adhesion of jigs and component parts used in production environments. Here are some examples of non-stick coatings. 【Selected Coatings (Partial)】 ■ Non-adhesive, slippery, chemical-resistant - Fluoropolymer coating ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-coat ■ Resin release at high temperatures - FSR coating ■ Prevention of adhesion of high-adhesion substances - Adhesive release coating - MRS coating (silicone-based coating) ■ Release properties, precision (precision parts, precision molds) - Nano process *For more details, please refer to the PDF materials or feel free to contact us.
