What is the role of organotin in one-component polyurethane waterproofing coatings?
It is used as a catalyst to improve the reaction speed of the synthesis or the drying and curing speed when used.
One-component polyurethane refers to polyurethane resin with NCO base, i.e., it is used without adding curing agent, and the resin is directly coated on the desired location, and then exposed to air and cured by reacting with the trace moisture in the air to produce a polymer with excellent properties.
