PBI/PI coating with excellent plasma resistance, heat resistance, and electrical insulation.
PBI coating - PI coating
It withstands friction heat without wearing out and the coating effect lasts!
PBI (Polybenzimidazole) and PI (Polyimide) possess the highest heat resistance among super engineering plastics and are ultra-super engineering plastics that excel in electrical insulation and other properties. At Yoshida SKT, we have developed a technology to apply PBI and PI, which have traditionally been used as plastic molded products, as coatings on the surfaces of metal products and other materials. This coating process allows us to enjoy the excellent functions and properties of super engineering plastics while also gaining advantages in cost and durability that molded products do not offer. *For more details, please refer to the catalog or contact us directly.

Company information
To maximize the performance of manufacturing equipment and machine parts, Yoshida SKT derives the "optimal solution" tailored to our customers from hundreds of surface treatment technologies. - Decreased productivity due to adhesive troubles - Instability in product quality due to friction - Early deterioration of equipment due to corrosion We respond to these challenges in the manufacturing field with our extensive track record and reliable technical expertise. In 1963, we began fluoropolymer processing. In 1968, we signed a licensing agreement with DuPont (now Chemours), supporting manufacturing innovations for over 2,000 customers across various industries, from automotive to medical and aerospace. Furthermore, in 2024, we are focusing on the development of next-generation products, such as PFAS-free coatings, contributing to the advancement of sustainable manufacturing. With a three-base system in Nagoya, Tokyo, and Yamaguchi, we flexibly respond to both mass production and custom orders. Our consistent quality management system ensures that we deliver reliable quality. For solving challenges in the manufacturing field, trust the surface treatment experts at Yoshida SKT.
