PLH52-3 Epoxy Glass Flake Topcoat

Overview
Two-component epoxy glass flake topcoat with resistance to water and permeation of chemical media, used for long-term heavy-duty corrosion protection.​
It is stated as suitable for underwater or humid environments and heavy chemical areas, and may also be used as an intermediate coat.​

Composition
Epoxy resin, glass flakes, pigments, additives, and solvents; modified amine curing agent; supplied as Part A & Part B.​

Typical uses

• Long-term heavy-duty corrosion protection topcoat (or intermediate coat) for steel structures and concrete facilities in underwater/humid environments and heavy chemical areas.​

Technical data (typical)

• Appearance / color: Various colors.​

• Theoretical consumption: 0.36 kg/m² at 150 µm DFT (losses not included).​
