HYDROSILYLATION CURE OF SILICONE RESIN CONTAINING COLLOIDAL SILICA AND A PROCESS FOR PRODUCING THE SAME

摘要

A hydrosilylation reaction curable composition including a silsesquioxane polymer, a cross-linking compound, a hydrosilylation reaction catalyst and colloidal silica having a surface coating formed thereon. The curable composition is cured to form a cured resin having high fracture toughness and strength without the loss of elastic modulus and glass transition temperature.
