PEEK coating on the inner surface of the tank | Prevents ion leaching and corrosion!
PEEKCOAT
"Metal-free and PFAS-free liquid connection part" High chemical resistance and adhesion! Protects the tank from acids and alkalis and prevents metal contamination of the chemicals.
This is a technical case study of our unique PEEK coating "PEEKCOAT" applied to the inner surface of metal pharmaceutical liquid tanks used for storing and transporting various chemical agents and refined liquids. *The images shown are cross-section samples of a small test tank that has been cut in half to confirm the condition of the inner surface application.* In corrosive chemical solutions and high-purity processes, applying this coating to the tank's inner wall achieves "excellent corrosion resistance" and a "metal-free environment." **Main Improvement Effects from Implementation** ■ Overwhelming corrosion resistance to strong chemicals It excels in resistance to acids, alkalis, and various organic solvents, effectively preventing tank corrosion and degradation from chemical solutions for an extended period. ■ Suppression of metal leaching (metal ion elution) The entire inner surface is coated with PEEK resin, eliminating direct contact with metals, preventing metal contamination in semiconductor and pharmaceutical processes, and maintaining the purity of the chemical solutions. ■ Reduced peeling due to high adhesion and thermal cycling High substrate adhesion minimizes the risk of cracks and peeling caused by temperature changes (thermal cycling) and liquid flow stress during liquid transfer. ■ Completely PFAS-free compliance By not using organic fluorine compounds, we can avoid future environmental regulation risks.

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.
