1,1,3,3-Tetramethyl-1,3-divinyldisilazane Usage And Synthesis

Chemical Properties

Clear liquid with ammonia odor

Uses

1,1,3,3-Tetramethyl-1,3-divinyldisilazane is used for silicone rubber, silicone resin, silicone gel and vinyl manufacturing.

Application

1,1,3,3-Tetramethyl-1,3-divinyldisilazane, a vinylsilazane, could cross-linked with polyhydromethylsiloxane in the presence of Karstedt's catalyst. When the reactions were carried out in solvent-free conditions, non-porous polysiloxane-silazane networks were obtained[1].

Flammability and Explosibility

Flammable
