Liquid alkoxysilyl-functional silicone resins, method for their preparation, and curable silicone resin compositions

摘要

Liquid alkoxysilyl-functional silicone resins having excellent storage stability and a method of preparing these liquid alkoxysilyl-functional silicone resins comprising running an equilibration polymerization reaction with components comprising (A) a polydiorganosiloxane and (B) an alkyl polysilicate in the presence of (C) an equilibration polymerization catalyst. Curable silicone resin compositions comprising the aforesaid liquid alkoxy-functional silicone resins which have excellent curability and when cured form a water-repellent coating on a variety of substrate surfaces.
