Product Introduction:
This product is a thermosetting epoxy-modified heavy-duty anti-corrosion powder coating specifically designed for reinforcing steel. The formulation uses partially imported functional epoxy resins and dedicated anti-corrosion curing agents. It features excellent reactivity, strong adhesion, good flexibility, and bendability, as well as superior resistance to chemicals, solvents, cathodic disbondment, and impact.

 

Product Usage:
Widely used for corrosion protection of reinforcing steel in bridges, ports, airports, buildings, basements, high-speed railways, and other infrastructure projects.

 

Product Features:

1. Excellent adhesion to the substrate.
2. Dense, continuous, bright coating with low permeability and minimal pinholes.
3. Superior cathodic disbondment resistance and high electrical insulation.
4. High bond strength with concrete.
5. Good flexibility, does not crack when bent.
6. Low melting temperature, high reactivity, high curing completion rate, and good mechanical properties.
7. Versatile and low powder consumption.
8. Reduces or eliminates stringing during the powder coating process.
