Detailed Product Description

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.



■ 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
