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