Single-component waterproofing coating is a polymer waterproof coating of reactive type of moisture-curable film. It is made of isocyanate and polyether as main material, mixing with solid agents, plasticizers and other additives using special technology by high temperatures dehydration and polymerization. Coating it in the surstrate, through the reaction between NCO end group in polyurethane prepolymer and moisture in air, which forms tough, soft and jointless rubber waterproofing film on the substrate.
Product characteristics
l Single-component waterproofing coating, easy to apply, the requirement to moisture content of the base is not high, it can be applied on the more moist surface, also available on the surface it's relative humidity is more big.
l Polyurethane coating film has high strength and elongation, good elasticity, good high temperature and low temperature resistance, and high adaptability to substrate shrinkage and cracks.
l Can coat 1mm to 3mm thick one time, coated film is dense, no bubbles, and high bonding power.
l Not necessary to brush the substrate treatment agent on the various substrate which is up to the standard
Applicable scope
Widely used in roofs, basement, toilet, swimming pool, and all kinds of industry and civil building waterproofing

Application technology
Ingredient and dosage: according to application dosage, evenly mixing round o use.
Reference dosage: coating film dosage is about 1.3-1.5kg/sqm when the thickness is 1mm.
Protection layer: on the coating film surface should do insulation protection as the design.
