Product Description
STWD8032 is a high-performance two-component anti-corrosive decorative topcoat based on aliphatic polyaspartic ester resin prepolymer as the main film-forming material, featuring excellent color fastness and weather resistance.
Product features and advantages
High solid content and low viscosity with good leveling property; the coating is tough, dense, full, bright and bright-colored
Strong adhesion to substrates and good compatibility with polyurethane, epoxy and other materials
High hardness, excellent scratch and stain resistance
Superior wear and impact resistance
Good corrosion resistance to acids, alkalis, salts and other media
Non-discoloring, non-yellowing, non-chalking and anti-aging, with outstanding weather resistance, gloss and color retention
Solvent-free of benzene series and lead-free, environmentally friendly
Excellent waterproof performance
Applicable for construction at a low temperature of about -10ºC, forming a dense coating with fast tack-free time
Application scopes
Anti-corrosion, protection and decoration of the surfaces of various reinforced concrete and metal structures.
