Surface treatment case: Surface treatment to prevent adhesion of fluororubber.
Super Alloy Coating
For preventing sticking of rubber products! Alloy-based non-stick coating that provides non-adhesive properties.
We would like to introduce a case of surface treatment that prevents the sticking of fluorine rubber and improves product productivity. ■Problem In the process of punching and cutting fluorine rubber sheets, the sheets were fixed with a pressing plate to prevent them from shifting during punching. However, the rubber sheets would stick to the pressing plate, causing the sheets to shift, wrinkle, and resulting in trouble with maintaining their fixed position. ■Background The customer was using a coating with a textured surface from another company on the pressing plate, but it was not sufficiently preventing adhesion, and the issues with rubber sticking persisted, leading them to consult us. ■Adopted Coating Super Alloy Coating ■Adoption Process and Effects At Yoshida SKT, we prepared test pieces and had the customer try out the adhesion of the actual rubber sheets. By adopting the Super Alloy Coating, we were able to effectively prevent the sticking of the rubber, making positioning smoother and improving production efficiency. *For more details, please visit the official Yoshida SKT website or contact us.

basic information
Super Alloy Coating is a coating system that covers the surfaces of soft substrates such as plastics and rubber, as well as lightweight metals like aluminum and thin sheets, with an alloy that has a hardness of Hv 600 or higher, while also possessing flexibility. It effectively prevents dirt on various manufacturing equipment and components, reduces maintenance tasks such as the removal of adhesive materials, and demonstrates excellent mechanical strength and durability. The unevenness of the coating is rounded, which minimizes scratches on contact objects. Additionally, despite being a metallic coating, it has the ability to conform to slight bends and can accommodate curved surfaces. It allows for excellent release properties from adhesive materials and strength while maintaining the flexibility of the processed material. 【Features】 ■ Non-stick convex surface coating ■ Alloy coating with Hv hardness of 600 ■ Excellent mechanical strength and durability ■ Reduces scratches on contact objects ■ Can be processed into various materials 【Product Lineup】 ■ Plastic and rubber processing series ・Silicone-based (processing temperature RT to 80°C) ・Fluorine-based (processing temperature 130 to 180°C) ■ Heat-resistant substrate processing series ・Fluorine-based (processing temperature 300 to 400°C) *For more details, please refer to the PDF document or feel free to contact us.
