Biogo-S single-component polyurethane waterproof coating is reaction-type, moisture-curing, and film-forming macromolecular waterproof coating. With isocyanate and polyether polyalcohol as the main material, and mixed with several assistants and filling materials, the product is made through addition polymerization reaction. In construction, the coating is directly painted on waterproof base layer. -NCO end group in polyurethane pre-polymer will react with moisture in air to form tenacious, flexible, and seamless rubber waterproof film on the surface of base layer.
● Single packaging and open-to-use feature for convenient construction;
● Pure polyurethane film for high tensile strength, better elongation, and excellent high and low temperature performance to withstand shrinkage and expansion of base layer caused by temperature or stress variation;
● Low requirement on base layer moisture content to make it possible to construct on humid base layer and to reduce the influence of air humidity;
● High adhesive strength to assure strong adhesion with various qualified base layers; free from base layer treating agent; formed film is able to withstand long-term immersion of water;
● The formed waterproof film has outstanding fastness to water, corrosion, and fungus;
● No special requirement on the thickness of single coating, and the formed film is compact, without pinhole or bubble;
● Various colors to meet customers’ personalized demand on surface color;
The product may be applied in waterproof construction for roofing, basement, bathroom, swimming pool, and a variety of civil and industrial buildings. It is also applicable to waterproofing of places with complicated shapes and crisscrossed pipes.
