Polyurethane enamel (2K) for steel or concrete protection in corrosive environments.
For metallurgy, power, petrochemical, bridges, ports, terminals.
Mixing ratio 18:3; surface dry 1 h at 25°C.
Compatible over polyurethane or epoxy intermediate coatings.
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.
