single-component polyurethane waterproof coating

High-strength&High-elasticity single-component polyurethane waterproof coating, environment-friendly

Single-component Polyurethane waterproof coating

1. Characteristics-- It is safe and environment-friendly product without solvent or pollutants. And it hasapproved tests by state related testing bodies so it is applicable directly to dinkingwaterproof works.

-- As mono-component product, it is easier to handle. And coating application is simple.--Compose of pure polyurethane, the coating film is featured with rubber's properties. Highelasticity, strength, extensibility and adhesion.-- It is applicable to heavy-film coating, and the film has high compatibility without pinholesor bubbles.--The film is generated by chemical reaction, featured with water-resistance, corrosionresistance, and fungus resistance.

-- It is featured with good physical and mechanical properties, high resilience, anti-fatigue,aging resistance. Its tensile strength reaches as high as 3Mpa with elongation at break600%.-- Good weatherability makes it adaptable to drastic changes of weather regardless of hot orcold.--Water-curing Mechanism makes the scope of its application wider.

2. Applications

-- Its applicable to waterproof and moisture works of roofing, external walls, basements,balconies, kitchens and lavatories.-- It is suitable for special buildings like granaries, civil air defense works, and bridge projects.
