ST27 is a liquid-applied, permanent elastic, cold applied and cold curing, one component polyurethane membrane used for long-lasting waterproofing. Solvent based. This product can be applied on wet surface and complicated projects with its unique mechanism of reaction by atmospheric moisture with ground to form a seamless, strong bonding, elastic and flexible waterproof film.
Advantage:
- Packed in one component and ready to use. It avoids the quality instability induced by the inappropriate compounding of two or three components;
- Stable performance. It possesses the property of aging resistance, acid and alkali resistance, fatigue resistance as well as high and low temperature resilience; and resistant to common chemicals.
- Low VOC, environmentally Friendly;
- Good leveling property, easy installation. After coating, it will react with moisture in the air and cure, forming a compact, seamless, tough and high elastic waterproof film;
- Excellent crack coverage and sealing ability
- Excellent thermal shock resistance and does not soften when exposed to high heat
- Completely adheres to all surfaces.
- Weather resistant
Application
- Roof, underground waterproofing projects, kitchen & bathroom;
- Not for food-grade water project;
- Car park,bridge and bridge surface
Consumption: 1mm thickness coating is about 1.2-1.5kg/m2/2 layers
