1,1,3,3,5,5-Hexamethylcyclotrisilazane

Name: 1,1,3,3,5,5-Hexamethylcyclotrisilazane
Brand: Dongguan City Betterly New Materials Co., Ltd.

Hexaphenylcyclotrisilazane is one of the most important cyclosiloxanes. It has good hydrolysis stability because its phenyl groups have high steric hindrance. It can effectively improve heat resistance of silicone rubber if it is applied into heat resistance agent to prevent oxidative crosslinking and main chain degradation of silicone rubber side chains. And when it is heated at temperature of 400℃ for a long time, it can be formed into polymer for a good heat resistance coating.
