It is a discoloration preventive agent for trivalent chromium plating and tin-based alloy plating.
Decorative plating, particularly tin-based alloy plating and trivalent chromium plating, has widely utilized hexavalent chromium electroplating as a post-treatment to improve corrosion resistance. However, due to environmental considerations, there has been a growing demand for alternative treatments to electroplating. Chromium-free ACR is a corrosion protection agent that does not use hexavalent chromium at all. For more details, please contact us.

Company information
We develop, manufacture, and sell surface treatment chemicals based on electrodeposition paint. All of our electrodeposition paints are lead-free and tin-free. We offer a wide range of applications, from decorative purposes to functional uses. For functional purposes, we have options for electrical insulation (epoxy-based), heat resistance (polyimide-based), non-contamination (fluorine-based), and photoresist (alkali-resistant), among others. In the plating sector, we provide tungsten alloy plating with excellent release properties for glass and resin, as well as nickel plating processes with excellent solder wettability. We pursue the potential of surface treatment technology and aim to create added value for our customers. We have obtained ISO 14001 certification and ISO 9001 certification (for electrodeposition paint). For more details, please visit our website.
