Composition
This product is composed of two components: an emulsion and a color paste. The main resin system consists of epoxy resin, isocyanate crosslinking agent, and toughening agent, which form an emulsion after acid neutralization. The dispersion resin is based on epoxy resin, combined with pigments and fillers that are ground into a color paste.

Features

Application Performance: Excellent product stability, outstanding anti-aging performance, and fast film-forming speed.
Coating Performance: Superior coating appearance and mechanical properties.
Eco-Friendly: Water-based and free of lead and other heavy metals, making it an environmentally friendly coating.

Applications

Widely used in the anti-corrosion coating of automobiles, auto parts, home appliances, hardware, agricultural machinery, and various steel components.
It is well-suited for iron, aluminum, and alloy substrates.
