Sinomaco 2 part oil based polyurethane waterproof coating is a reactive curing two component high polymer waterproof coating consisting of A and B part. The part A is a kind of prepolymer prepared by polymerization of polyether resin and diisocyanate; and component B consists of vulcanizing agent, catalyst, resin, etc. Components A and B are mixed in a certain proportion, stirred evenly, coated and scraped on the bottom layer, and an integral and rubber elastic waterproof membrane will be formed after curing reaction.
The A part is a polyurethane prepolymer in white color and the B part is the curing agent in black color. Upon applycation, both A and B components will be mixed according to a certain ratio, normally 1:2. then to be applied on the working surface of the construction buildings, and after reaction, it will cured into a continuous, flexible and seamless rubber waterproof layer in black color through reaction for waterproofing.
