PLS52-1 Polyurethane enamel

Overview
Two-component polyurethane enamel for protective finishing on steel structures or concrete surfaces in corrosive environments.​
Provides resistance to water, boiling water, oil, and benzene solvents, and offers weather resistance for outdoor service.​

Composition
Formulated with polyurethane resin, high-grade weathering- and corrosion-resistant pigments, additives, and solvents.​
Cured with TDI trimer; supplied in Part A & Part B packs.​

Typical uses
For steel structures or concrete surfaces in corrosive environments, including metallurgy, power, petrochemical, bridges/ports, and terminals.​
