"Non-stick" refers to the property of being easy to release from strongly adhesive materials, meaning it either does not adhere or adheres with difficulty. For example, fluoropolymer resins excel in water and oil repellency, have a large contact angle, and possess a property of being difficult to wet due to their molecular structure. The measure of wettability, known as "critical surface tension (γc)," is extremely low for fluoropolymer resins, making them resistant to liquid adhesion and difficult to wet. Coatings that leverage such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Selected Coatings (Partial)】 ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Resin release at high temperatures - FSR Coating ■ Prevention of adhesion of high-viscosity materials - Adhesive Release Coating - CTT Fabric Sheet - MRS Coating (Silicone-based coating) *For more details, please refer to the PDF materials or feel free to contact us.

There is an electrical insulation coating with high electrical resistivity that has the function of blocking electric current. Fluororesin has high insulation properties, with a volume resistivity of Ω·cm or more, and its arc resistance is more than three times that of general-purpose resins, making it superior and stable in various electrical environments compared to other resins. On the other hand, if the coating surface is prone to charging, leading to issues such as the adhesion of foreign substances due to electrostatic attraction or electrostatic disasters, you can select a fluororesin coating with antistatic properties.

Wear refers to the phenomenon where 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 type is "rough wear," which occurs when surfaces are abraded and eroded due to contact with rough surfaces or particulate matter. The other type 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 Coatings] ■ 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.

When applying non-stick coatings to molds and jigs, there are applications that cannot be used due to wear or film peeling. For example, molds subjected to strong pressure and "heat sealers" in packaging machines that come into contact with metal are among them. 'Bicoat' is a coating system that achieves the ideal functions of non-stick and wear resistance by combining inorganic and organic surface treatment technologies. ◆ It offers reliable non-stick and release properties, as well as high hardness and excellent dimensional accuracy. ◆ It is also suitable for coating areas that require micron-level dimensional precision. 【Features】 ■ Incredible durability ■ High hardness and scratch resistance ■ Excellent wear resistance ■ Superior non-stick and release properties ■ Safe for use in molds requiring micron-level dimensional precision *For more details, please refer to the PDF document or feel free to contact us.

When considering the adoption of coatings, if the equipment or parts to be coated are used in a high-temperature environment, the impact on the coating must also be taken into account. Fluororesin boasts remarkable heat resistance among resins and is a material that is difficult to melt or deform even at high temperatures. Depending on the type of fluororesin, the continuous maximum operating temperature is considered to be 260°C (JIS K 7226). Fluororesin coatings can be used at high temperatures or ultra-low temperatures. [Selected Surface Treatments] ■ Heat and Cold Resistance - Fluororesin Coating (Teflon Coating) ■ Ultra Heat Resistance - SGN Coating - PBI Coating *For more details, please refer to the PDF materials or feel free to contact us.

It is a surface treatment to obtain properties that prevent deterioration or alteration caused by chemical substances (chemical resistance) and functions that protect against dirt by making it difficult for water to penetrate. Fluororesin, due to its structure, has extremely excellent chemical resistance against most acids, alkalis, and organic solvents, and it is also a material with very low water absorption. Therefore, fluororesin coatings are suitable for protecting substrates from corrosion caused by chemicals in an all-around manner. 【Selected Coatings (Partial)】 - Chemical resistance and heat resistance - Fluororesin coating (Teflon coating) - MY lining (R) *For more details, please refer to the PDF document or feel free to contact us.

"Release properties" refer to the ability of a mold to release from the cast, and it is often used with a similar meaning to non-stick properties. Non-stick properties refer to the characteristic of not adhering to or being difficult to adhere to strongly adhesive substances. Surface treatments with excellent release properties often use materials such as fluororesin and silicone, which have low surface free energy and, due to their molecular structure, possess properties that make them difficult to wet. Surface treatments that utilize such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Selected Coatings (Partial)】 ■ Non-stick, slippery, heat-resistant - Fluororesin coating ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Resin release at high temperatures - FSR coating ■ Prevention of adhesion of high-viscosity substances - Adhesive release coating - CTT fabric sheet - MRS coating (silicone-based coating) ■ Release properties, precision, water repellency, oil repellency, liquid runoff (precision parts, precision molds) - Nano process *For more details, please refer to the PDF document or feel free to contact us.

With the expansion of electric vehicle (EV) adoption, the tire industry is rapidly developing EV-specific tires that have different performance characteristics compared to traditional gasoline vehicles. Among these, SSBR is gaining attention as a material that significantly improves tire performance due to its unique molecular structure compared to conventional styrene-butadiene rubber (E-SBR). On the other hand, SSBR is inherently a highly adhesive substance, increasing the need for non-adhesive coatings in the manufacturing process. [Need for Non-Adhesive Coatings in the Manufacturing Process] ■ Adhesion prevention is necessary during the storage and transportation of uncured rubber. ■ Adhesion prevention is necessary when handling extruded products and pre-formed products. ■ Adhesion prevention is necessary in the tire manufacturing process. If you are experiencing troubles or decreased productivity due to adhesion issues in the manufacturing process, please consider non-adhesive coatings. Yoshida SKT offers a variety of coating options. We will propose non-adhesive coatings that match each process. *For more details, please refer to the PDF materials or feel free to contact us.

**Basics and Types of Release Coatings** Release coating is a surface treatment technology that involves applying a special coating to the surface of molds and forming machines to prevent molded products from sticking to the molds, allowing for smooth removal. By improving release properties, it enables shorter production cycles and stabilizes product quality. In manufacturing sites troubled by release issues with molds, outsourcing coating to contract processing manufacturers with specialized technology allows for high-quality surface treatment that may be difficult to achieve in-house. **Main Types of Release Coating Technologies** There are various types of release coatings, and the optimal method is chosen according to the application. - **Silicone-based Coatings:** Particularly excellent for molten resins and adhesive release. - **Fluoropolymer (Teflon) Coatings:** Using materials like PTFE, PFA, and FEP, they exhibit high release effectiveness. - **Ceramic Coatings:** Ideal for applications requiring high durability due to their excellent wear resistance. It is important to select these coating technologies based on the substrate and usage environment, and release coating manufacturers provide optimal processing. *For more details, please refer to the PDF document or feel free to contact us.*
