Measures against film thickness defects and cracking at corners caused by fluororesin coating and PEEK coating.
In fluororesin coatings and PEEK coatings, the way the coating adheres varies depending on the shape of the substrate. In particular, at corners and edges, variations in film thickness are likely to occur, which can lead to issues such as coating cracking, peeling, and reduced corrosion resistance depending on the conditions. Special attention is required for corner pipes, bent sheet metal, and sharp edge components. Our company offers suggestions for R processing and optimizes coating specifications according to product shapes and painting methods, reducing variations in film thickness and the risk of coating defects. To ensure stable durability and chemical resistance, it is important to design shapes with coating in mind. If you have concerns about corner shapes, please feel free to consult us.

basic information
In fluororesin coatings and PEEK coatings, the application of paint through spray or powder coating varies depending on the shape of the substrate. Particularly at corners, the movement of paint particles, surface tension, and static electricity can lead to an uneven thickness distribution of the coating. This may result in insufficient thickness on protruding areas and paint accumulation in recessed areas. Additionally, in electrostatic powder coating, the Faraday cage effect can make it difficult for the powder to reach recessed areas. As a result, issues such as pinholes, reduced corrosion resistance, coating cracks, and peeling can occur. Our company offers suggestions for R processing and optimization of coating conditions based on corner shapes and applications.

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.
