High-durability PEEK coating resistant to wear and chemical environments, achieved through thick film processing of up to 3000μm.
PEEK coating has excellent mechanical strength and chemical resistance, but traditionally it has been difficult to ensure film thickness, with thick films generally being around 300 to 500 μm. As a result, there were limitations in durability in extremely harsh sliding environments, such as sliding parts subjected to high loads. Our company has adopted a layered process that repeats painting and firing multiple times, allowing for thick films of up to 3000 µm. This process achieves stable film formation while minimizing the risk of cracks and peeling due to internal stress and thermal expansion differences. The increased thickness makes it easier to secure wear allowances, contributing to the longevity of sliding and transport components. It can also be applied to applications that were difficult to address with conventional thin-film PEEK coatings.

basic information
PEEKCOAT is a coating that leverages the characteristics of PEEK resin, such as high mechanical strength, wear resistance, chemical resistance, and heat resistance. It contributes to extending the lifespan of components and reducing maintenance in harsh operating environments. - Our unique process of repeated painting and firing allows for the formation of thick films up to 3000µm. - We have a track record of application primarily on metal substrates such as aluminum, iron, and stainless steel. - By adjusting the coefficient of linear expansion and optimizing primer design, we achieve both adhesion and durability.

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.
