Product Description

Key-211 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.

Features

Serves as a primer protective coating for unchromated light metals.
Delivers outstanding corrosion resistance and oxidation resistance.
Dust-repellent and anti-adhesive properties enable easy cleaning and maintenance with exceptional scratch resistance.
Supports surface coloring and personalized decorative designs, achieving rich metallic effects.
Meets customers' high-precision requirements for product dimensions across multiple dimensions.
Combines high-temperature protection with resistance to sudden temperature changes.
Significantly cost-effective, requiring only 1/10th the coating volume per unit area compared to conventional coatings, substantially reducing overall operating costs.
