Product Description
Seal 935 is a silane modified polyurethane resin based on high molecular-weight polyether, end-capped with siloxane and containing carbamate groups, has the characteristics of high activity, no dissociative isocyanate, no solvent, excellent adhesion and so on. It is curing mechanism is moisture curing. Catalysts are needed in sealant formulation. Ordinary organotin catalysts(such as dibutyltin dilaurate) or chelated tin (such as diacetylacetone dibutyltin) can achieve good mechanical properties.
