Two-component polyurethane waterproof coating
Two-component polyurethane waterproof coating is a kind of two-component curable reaction type waterproof coating. Component A is a prepolymer made by polymerization of polyether resin and diisocyanate, and component B is refined from a variety of additives such as vulcanizing agents, catalysts, resins, etc. The components A and B are mixed and stirred evenly in appropriate proportion, and then applied on the base surface. After curing, a low-toxicity, low-odor, overall and flexible coating film is formed.
This product does not contain coal tar. It has little irritating odor, less environmental pollution, excellent extensibility, high tensile strength and stable and reliable performance. In addition, it also plays a role in bridging the expansion and cracking deformation of the waterproof base.
Scope of application
It is applicable for waterproofing, moisture-proofing and -seepage-proofing of concrete, bamboo, wood, steel, asbestos tile structure roofs and internal and external walls, basements, kitchens, toilets, pools with non-edible water and other buildings.
