Product Description

Product Introduction

BNU-912 one-component polyurethane waterproof coating is prepared by the reaction of special polyether polyols and isocyanate to form a prepolymer, which is prepared by polymerization with various auxiliaries and fillers. Does not contain crosslinking curing agent, completely by absorbing moisture in the air and curing into a film. This kind of coating is a wet curing type of coating, with high strength, large elongation, good water resistance and other characteristics, the formation of a layer of tough seamless coating on the surface of the base layer, the deformation of the base layer is strong, belongs to a new generation of environmental protection technology new materials.

BNU-914 two-component polyurethane waterproof coating is cured by reaction of two components A and B to form A film, and component A is made of polyether polyols and polyisocyanate. The light yellow transparent viscous liquid containing terminal isocyanic acid group generated by polymerization reaction: Component B is a paste processed by mixing crosslinking agent, accelerator, toughening agent, viscosifier, mildewproof agent, filler and pigment. When used, the A and B components are mixed in a certain proportion, stirred evenly, scraped on the base surface, and reacted and cured for several hours to form a resilient, tough and durable waterproof film.
