An alternative to fluoropolymer! "Biceram" using the sol-gel method. A surface treatment that balances regulatory compliance with a scratch resistance of "pencil hardness 9H."
Amid the tightening global regulations on per- and polyfluoroalkyl substances (PFAS), there is an urgent need to explore "fluoropolymer alternative technologies" in manufacturing. ■ Ceramic Coating "Biceram" This is a surface treatment technology that is completely free of organic fluorinated compounds [PFAS-free]. It complies with Japan's "Food Sanitation Act (Ministry of Health, Labour and Welfare Notification No. 370)" standards, making it safe and secure for use in parts and molds of manufacturing machinery that come into direct contact with food, as well as cooking utensils. ■ Composition of the Coating The technology is based on the "sol-gel method," which produces a dense ceramic solid from a liquid. By incorporating a silicone release agent that exhibits non-stick properties at the molecular level within a robust three-dimensional silica network, we achieved excellent initial release properties and scratch resistance that significantly surpasses that of fluoropolymers, reaching a pencil hardness of 9H. This is ideal for those who want to evaluate alternatives in anticipation of future regulatory tightening and are looking for a safe, scratch-resistant release coating.

basic information
【Method】 Sol-gel method (heating treatment via liquid phase process) 【Components】 Organic-inorganic hybrid (silica matrix + silicone release agent) 【Environmental and Safety Standards】 ■ No use of per- and polyfluoroalkyl substances (PFAS) (PFAS-free) ■ Compliance with the Food Sanitation Act (Ministry of Health, Labour and Welfare Notification No. 370) 【Coating Properties】 ■ Coating hardness: Pencil hardness 9H (hardness resistant to contact with metal scrapers, etc.) ■ Heat resistance temperature: Approximately 200℃ to 250℃ 【Process Advantages】 Since it is baked at a lower temperature than the usual ceramic sintering temperature, thermal impact on the substrate is minimized. The "liquid application" process allows for uniform coating thickness on complex three-dimensional shapes, fine irregularities, and inner surfaces. *Due to the behavior of gradually consuming the release components during use (self-sacrificial film behavior), prior application evaluation is recommended.

Company information
Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
