Main Application:
Because the active hydrogen of the end-side hydroxyl is replaced by the methyl, so the reaction of the hydroxyl with siloxane bond is avoid when it have the hydrosilation reaction. It reduce the viscosity of the product effectively and improve the quality of the effective content. It improve the quality of the polyether modified silicone oil, reduce the incidence of adverse reaction greatly. The stability of the storage was better, especially for these conditions as hydrolysis and have long storage period. It can be widely used as stabilizer agent for polyurethane foam, emulsifier, personal protective product, coating leveling agent, softener for the hydrophilic antistatic fabric, self-emulsifying defoaming agent, water-soluble lubricant, glass antifogging agent and crosslinking sealant. Si C polyether modified silicone used in chemical fiber oil agent.
