Decription
Silicone PU-Base layer (SPU-001P)is kind of one component polyurethane material. It is used on concrete base, inorder to seal with the water vapor and improve the bond between the concretelayer and elastic layer.
Feature
High permeability and excellent sealing performance, will improve thestrength of the substrate. Strong adhesion to the substrate,the coating has excellent alkali, acid and waterresistance, and has good compatibility with the surface layer.
