PF680 Waterproof Weather Resistant Polyaspartic coating
Products introduction
PF680 Waterproof Polyaspartic Topcoat consists of Polyaspartic resin, non-yellowing HDI trimer isocyanate, additives and small amount of solvent.
Characteristic
■ Suit for high build application, one time film thickness more than 300μm
■ Excellent weather resistance, color stable in 20 years
■ Good adhesion to epoxy primer and Polyaspartic topcoat
■ Excellent impact resistance and break elongation
■ Convenient application, fast drying
Designed application: for waterproof and anti-corrosion of concrete substrate(basement,bridge,roof,warehouse etc), for buried steel structure waterproof and anti-corrosion of outer layer
