Single-Component Polyurethane Waterproof Coating
Overview:
Single-Component Polyurethane Waterproof Coating is a reactive wet curing film-forming polymer waterproof coating. It is made of isocyanate and polyether as main materials, mixed coagulant, plasticizer and other auxiliaries by special process through high-temperature dehydration and polymerization. It is coated on the waterproof base course during application. Through the chemical reaction between - NCO end group in polyurethane prepolymer and moisture in the air, a tough, soft and jointless rubber waterproof membrane is formed on the surface of the base course.
Features:
1. Single-Component Polyurethane Waterproof Coating can be used after mixing evenly on site, and convenient to use. No strictly requirement of the water content of the base, and the construction can be carried out on the base surface without obvious water accumulation.
2. Polyurethane film has high tensile strength, high elongation, good elasticity, good resistance to high and low temperature, and strong adaptability to shrinkage and cracking deformation of base course.
3. 0.5~1.0mm thick at one time, and the film is dense without pinholes and bubbles.
4. The adhesive force is strong, and there is no need to brush the base treatment agent on the various base courses that meet the requirements.
5. The color is adjustable, which can meet the different humanized requirements of different customers on the surface color.
