Product Description

KEY-231 Hejie · PFAS-free anti-fingerprint nanocoating is a high-tech, environmentally friendly functional coating material prepared based on a sol-gel process.

Through organic-inorganic combination technology, it can form an ultra-thin protective film layer with a thickness of only 5-10μm on the surface of the substrate, and all performance indicators of the product strictly meet the requirements of national environmental standards.

Compared to traditional electrophoretic treatment processes, KEY-231 coating has the core advantages of long-lasting easy cleaning and high-strength corrosion resistance, while also having excellent wear and scratch resistance. While playing a protective role, it can effectively maintain the original heat dissipation efficiency of the substrate, enhance the gloss and texture of the metal surface, and ensure that the surface remains clean and bright for a long time.

Features

It is compatible with non-chromiumized light metal substrates and can be used directly as a base protective coating.
It possesses excellent corrosion resistance and oxidation resistance, providing long-lasting protection for the substrate.
The surface is stain-resistant and easy to clean, dust does not easily adhere to it, and it has excellent scratch resistance.
It supports customized surface coloring and decoration, and can accurately present a metallic appearance.
Excellent dimensional accuracy control, meeting customers' stringent process standards in multiple dimensions.
It combines high-temperature protection with resistance to sudden temperature changes, making it suitable for complex temperature-changing working conditions.
The amount of paint used per unit area is only about 1/10 of that of conventional paint, which greatly reduces the overall cost of painting.
