Application
1,3-Divinyl-1,1,3,3-tetramethyldisilazane serves as a versatile component in the manufacturing of silicone-based products, such as silicone rubber, silicone resin, and silicone gel. This compound, characterized by its clear liquid form and distinct ammonia odor, is especially valuable due to its ability to participate in cross-linking reactions with polyhydromethylsiloxane, facilitated by Karstedt's catalyst. These reactions, when performed without solvents, result in the formation of non-porous polysiloxane-silazane networks, making it an essential material in producing durable and efficient silicone and vinyl products.
