Polyurethane Waterproof Coating

Product introduction:

Beifang One Component Polyurethane Waterproof Coating is a high elastic waterproof material, reacting with moisture in the air after brushing

Execution standard:GB/T19250-2013” Polyurethane Waterproof Coating”
Specifications:20L
  • Advantage
  • Performance

1.Good construction performance: one component, out of the box for use on-site, easy construction; brushing 2-3 times up to 1.5mm thickness, dense coating, pinhole-free, no bubbles;
2.good rubber elasticity and resilience, high tensile strength, strong resistance to the deformation of base layer (shrinkage and cracking);
3.Good bonding property, strong adhesion: be bonded with different base layers and directly constructed on the qualified base layers;
4.Excellent water and corrosion resistance: forming film by chemical reactions, water erosion resistance, corrosion resistance, mildew resistance, especially suitable for long-term soaking parts of waterproof engineering constructions;
5.Environmental friendly, high boiling point solvents, non-dangerous goods, no benzene, toluene, xylene and any other toxic solvents, no coal tar.
