Brief introduction of STP resin End Silicon alkyl polyether prepolymer, namely PPG Polyether mainly chain, silicon oxygen alkyl end polymer, namely Silane modified Polyether, referred to as STP resin, also known as MS Resin. The characteristic structure of silane modified Polyether is the main chain is macromolecular Polyether, the end-base is the siloxane containing the hydrolyzed group, which has the structural advantages of both polyurethane sealant and silicone sealant, and the curing mechanism is that the end-base siloxane reacts with the moisture in the air to produce the end-base silicone alcohol under the action of the catalyst. The cross-linking reaction between silicone alcohol and silicone alcohol forms a flexible network structure, which realizes the solidification process from liquid to solid....Send Inquiry
