CAS: 1009-93-4

1,1,3,3,5,5-Hexamethylcyclotrisilazane is a crucial cyclosiloxane known for its excellent hydrolysis stability, attributed to the high steric hindrance of its phenyl groups. When used as a heat resistance agent in silicone rubber, 1,1,3,3,5,5-Hexamethylcyclotrisilazane effectively enhances thermal stability by preventing oxidative crosslinking and degradation of the rubber’s side chains. Additionally, prolonged heating at 400°C transforms 1,1,3,3,5,5-Hexamethylcyclotrisilazane into a polymer, creating a durable heat-resistant coating.
