PLH53-7 Epoxy Glass Flake Anti-Rust Intermediate Coating

Overview
Two-component epoxy glass flake anti-rust intermediate coating with barrier performance, waterproofing/anti-permeation properties, and chemical resistance.​
It is described as having strong adhesion, a tough and wear-resistant film, high mechanical strength, and long-term corrosion protection.​

Composition
Epoxy resin, glass flakes, anti-rust pigments, additives, solvent, and curing agent; supplied as Part A and Part B.​

Typical uses

• Anti-rust and anti-corrosion protection for steel and concrete substrates in ship, offshore engineering, underground mines, chemical areas, wastewater treatment and other heavy-duty corrosion environments.​

Technical data (typical)

• Appearance / color: Iron oxide red, light gray, white.​

• Theoretical consumption: 0.12 kg/m² at 50 µm DFT (losses not included).​

• Density / specific gravity: 13 kg/L.​

• Drying / curing (25°C): Touch dry 1 h; hard dry 24 h; full cure 7 days.​

Application data (25°C)
