Product Description

Composition
This product consists of two components: an emulsion and a color paste. The main resin system is composed of epoxy resin, isocyanate crosslinking agent, and toughening agent, which are neutralized with acid to form the emulsion. The dispersion resin is epoxy resin, and the color paste is prepared by grinding pigments and fillers.

 

Features

  • Application Performance: Excellent penetration and electrodeposition capabilities; outstanding anti-settling stability of the bath.
  • Film Performance: Excellent coating appearance and mechanical properties.
  • Environmentally Friendly: A water-based coating free of lead and other heavy metals, meeting environmental standards.

Applications

  • Widely used for corrosion-resistant coating of automobiles, auto parts, household appliances, hardware, agricultural machinery, and various steel components.
  • It is also suitable for electrophoretic coating of light industrial products with specific performance requirements, such as umbrella frames.
