Elastomer Waterproof Polyurea Coating
Product description
Elastomer waterproof polyurea material is a two-component elastomer material composed of component A and component B. Component A is a semi-prepolymer of the terminal NCO group. B component composed of amino-terminated polyether, amine chain extender and additives.
Polyurea coating can be used as a waterproof coating on the surface of concrete or other substrates, lining, medium-resistant layer, etc.
Polyurea features
●Polyurea coating can be used alone or in combination with other materials as a protective coating, anti-collision layer and reinforcement layer on the surface of concrete dams.
●Polyurea coating can form hard coatings with different thicknesses, and can be applied to various occasions with proper substrates processing.
●Polyurea coating is no catalyst, fast curing. And it can be sprayed on any curved surface, inclined surface and vertical without sagging phenomenon.
