Single-component Polyurethane Waterproof Coating

Introduction

High-strength & High-elasticity Single-component Polyurethane Waterproof Coating (Environment-friendly) is a flexible waterproof coating with isocyanate and Poly ether polyol as principal raw material plus some additives and fillers by poly addition reaction.

By coating it on the base and through the polyurethane pre polymerization reaction between NCO Terminal group and the moisture in the air, it forms into a layer of rubber waterproof film on the base surface, which is toughened, flexible, seamless.

Characteristics

1. Widely used product and world recognized quality.

2. As mono-component product, it is easier to handle. And coating application is simple.

3. Compose of pure polyurethane, the coating film is featured with rubber's properties. High elasticity, strength, extensibility and adhesion.
4. It is applicable to heavy-film coating, and the film has high compatibility without pinholes or bubbles.
5. The film is generated by chemical reaction, featured with water-resistance, corrosion resistance, and fungus resistance.
6. 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 break **0%.
7. Good weatherability makes it adaptable to drastic changes of weather regardless of hot or cold.
8. Water-curing Mechanism makes the scope of its application wider.
 

Applications

1. Its applicable to waterproof and moisture works of roofing, external walls, basements, balconies, kitchens and lavatories.

2. It is suitable for special buildings like granaries, civil air defense works, and bridge projects.

Attention
1. It is supposed to be sealed and stored upside down in a cool and dry place,avoiding direct sun exposure,humidity
2. During storage,there would be buildups on its surface.Just get rid of the buildups before application.
3. Unspent coating is supposed to be sealed timely un caseof curing and abandoned
4. In and after the progess of waterproof construction,protect it timely,guarding against artificial damage.
5. The storehouse or construction site should be kept away from fire.In the process of construction.,workers are supposed to be wearing protective clothing.
6. storage time is 6 months, If it is qualified enough beyond storage time, it can still be put into use.
