Acrylic polyurethane intermediate coating (2K) for film build and intercoat bonding.
Vehicles, ships, bridges, structural steel systems.
0.13 kg/m² at 40 µm; recoat 8 h.
Sandable; resists solvents and chemicals.
Overview
Two-component acrylic polyurethane intermediate coating for steel substrates where intercoat adhesion, sandability, and weatherable film build are required.
Performance focus: fast drying, hardness, adhesion between layers, sandability, and resistance to solvents and chemicals.
Composition
Part A: acrylic resin with pigments, fillers, and additives.
Part B: polyisocyanate curing agent.
Typical uses
Intermediate coating for automobiles, construction machinery, mining machinery, ships, bridges, and steel structures.
