Product Details


Introduction and Application

Octamethylcyclotetrasilazane is a solid low molecular polymer with a main chain composed of Si-N bonds. It can be used to prepare high-purity silazane precursors with the expected degree of polymerization by ring-opening polymerization. It can be used in the photovoltaic industry and semiconductor industry for weather resistance and self-cleaning protection. The activity of Si-CH3 bonds is insufficient, and it is difficult to heat cure when used alone. Therefore, it is often used in combination with organic silazanes containing active groups, such as methyl hydrogen silazane to prepare Si-C-N ceramic fibers.

Si-N can react with hydroxyl-containing substances and can be used as an amine curing agent. It can also modify hydroxyl-containing resins to improve temperature resistance and weather resistance, such as phenolic resins, epoxy resins, alkyd resins, acrylic resins, etc.

Silazanes are widely used in the rubber industry, ceramic industry, etc. For example, in the silicone rubber processing industry, silazanes are good additives. They can not only act as structure optimization control agents but also improve the heat resistance and mechanical strength of vulcanized rubber. Therefore, silazanes are added to other organic synthetic rubber processing industries to improve their thermal stability and mechanical strength.
