Heat-resistant coating that maintains release properties even at high temperatures *Materials available upon request.
At high temperatures, the coating becomes soft, reducing release properties and causing resin to adhere to the heat seal. A coating that maintains hardness and release properties even in high-temperature environments above 200°C.
In high-temperature processes such as resin molding, heat sealing, and high-temperature pressing, common coatings face challenges such as reduced film hardness and decreased release properties. Our company offers a lineup of coatings developed for high-temperature environments. "CHC (Ceramic Hard Coat)" minimizes the decrease in film hardness at temperatures above 200°C through the combination of ceramics and fluororesin, maintaining release properties for an extended period. 【Examples of coatings suitable for high-temperature environments】 ■ CHC: For resin molding molds (high-temperature release), heat sealing devices, components in contact with molten resin, and high-temperature pressing molds. ■ Fluororesin coating (PTFE): Heat resistance with a continuous use temperature of 260°C. 【Expected effects】 ■ Reduction of release failures and adhesion troubles in high-temperature processes. ■ Extension of reprocessing and replacement cycles due to the long lifespan of the coating. *For more details, please download the materials and check.
