Uniform application on complex shapes and inner surfaces! Sol-gel method ceramic coating.
Biceram
Suppresses thermal impact on the substrate with low-temperature baking. Coating on complex three-dimensional shapes and uneven surfaces. Achieves both pencil hardness of 9H and release properties.
Conventional ceramic coatings (such as thermal spraying and CVD/PVD) typically involve large-scale processes that require high-temperature plasma or vacuum equipment, which limits the shapes and substrates that can be coated. ■ Formation of Ceramic Coating Films by Sol-Gel Method Our "Biceram" utilizes the "Sol-Gel method," which is a liquid-phase process that involves applying a liquid (starting material) and then curing it. - A strong coating is formed at a lower temperature (200–250°C) than the usual ceramic sintering temperature, minimizing thermal impact on the substrate. - Due to the liquid process, it can coat complex three-dimensional shapes, fine irregularities, and the inner surfaces of pipes. - The coating itself has a hybrid structure that incorporates silicone release agents within a three-dimensional network of silica (SiO2). In addition to the "uniform applicability" unique to the Sol-Gel method, it simultaneously achieves scratch resistance that surpasses conventional fluororesins with a pencil hardness of 9H and excellent initial release properties.

basic information
【Coating Method】 Sol-gel method (liquid phase process through hydrolysis and polycondensation reactions of the solution) 【Main Component】 Ceramic matrix primarily composed of silica (SiO2) + silicone release agent 【Hardness】 Pencil scratch hardness 9H (resistant to scratches and maintains initial performance for a long time) 【Heat Resistance Temperature】 Approximately 200℃ to 250℃ 【Shape Compatibility (Process Features)】 ■ Ceramic formation at low temperatures Suppresses thermal distortion of the substrate ■ Compatibility with complex shapes Due to liquid application via spraying, coating is possible on "inner surfaces," "uneven surfaces," and "three-dimensional structures" that are unreachable by dry processes like thermal spraying. 【Safety】 ■ PFAS-free (no use of organic fluorine compounds) ■ Complies with Japan's Food Sanitation Act *Due to the behavior of the release components migrating to the surface within the silica framework, the release performance gradually decreases with use. We propose optimal usage strategies for extended lifespan.

Applications/Examples of results
There are many application examples for complex parts where masking for thermal spraying is difficult, or areas where fluororesin would get scratched. 【General Industrial Machinery and Automation Lines】 ■ Complex-shaped parts feeders, bowls, and chutes ■ Sealers for packaging machines and complex adhesive application jigs (Uniform application on complex shapes prevents snagging and adhesion of workpieces) 【Food Manufacturing Sector】 ■ Baking molds and dies for confectionery and bread with fine irregularities ■ Hoppers and cutter blades for food transport lines 【Resin Molding Sector】 ■ Complex molds for plastic and rubber molding (reducing the frequency of mold cleaning) Our company specializes in contract processing. We propose optimal specifications according to the difficulty of the shape and the usage environment (temperature, counterpart material, durability). We also accommodate prototype requests, so please feel free to consult with us.

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.
