Epoxy Anti-Corrosion Powder Coating for Reinforcing Steel
Product Introduction:
This is a thermosetting epoxy-modified heavy-duty anti-corrosion powder coating specifically designed for epoxy-coated reinforcing steel. The product uses imported two-step special epoxy resins, functional epoxy resins, and dedicated anti-corrosion curing agents. It features excellent reactivity, strong adhesion, good toughness and flexibility, and superior resistance to chemicals, solvents, cathodic disbondment, and impact. The formulation has been tested and proven effective by authoritative departments.
Product Features:
Excellent adhesion to the substrate.
Dense, continuous, bright coating with low permeability and minimal pinholes.
Superior cathodic disbondment resistance and high electrical insulation.
High bond strength with concrete and strong grip.
Good toughness, does not crack when bent.
Low melting temperature, high reactivity, high curing completion rate, and good mechanical properties.
Versatile and low powder consumption.
Reduces or eliminates stringing during the powder coating process.

Compliance Standards:
JG 3042-1997; GB/T 25826-2010
Application Fields:
Bridges, ports, airports, buildings, basements, high-speed railways, and other infrastructure projects.
Application Process:
Electrostatic spraying.
Precautions:
The reinforcing steel surface should be free of oxide scale, revealing the metal’s original color; the surface roughness should meet the standard, ideally 50-70 mm; the rust removal grade should reach Sa2 1/2 level (GB/T 8923), with no chloride residues. Preheating temperature should be controlled between 220-245°C.
The product should be stored in a well-ventilated, dry indoor environment with a temperature below 27°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure. The stacking height should not exceed four layers. Avoid long-term pressure and ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.
Due to the high reactivity of this product, the recommended storage period is within 3 months at 27°C. If used beyond the storage period, the performance should be verified in advance.
