Product Description
KEY-212 Heyun PFAS-free high-temperature resistant nanocoating utilizes sol-gel technology to produce a nano-scale organic-inorganic composite ultra-thin coating. This innovative high-tech eco-friendly coating meets all current environmental standards.
This coating can be widely applied to various metal substrates, with core applications in surface treatment for automotive and rail transit manufacturing components. It directly replaces traditional electrophoretic processes while offering long-lasting, easy-clean properties. Not only does it deliver high-strength corrosion protection, but it also imparts superior abrasion and scratch resistance to substrates. Simultaneously, it effectively maintains the substrate's inherent heat dissipation efficiency, enhances metallic luster, and ensures a long-lasting clean and glossy surface. With its outstanding comprehensive performance, it has gained high recognition in global high-end industrial manufacturing sectors such as automotive, rail transportation, and aerospace.
