1,1,3,3-Tetramethyldisiloxane is an organosilane reducing agent that can be used to reduce the formation of sulfides and reduce etherification reactions. It is used to produce addition silicone rubber, silicone gel, methyl hydrogen silicone oil and other special additives.
A hydrogen-terminated disiloxane that can undergo addition reaction with unsaturated olefins. Therefore, it is widely used to prepare hydrogen-terminated polysiloxanes, used as chain extenders or crosslinkers for silicone rubber; Chemicalbook or used to synthesize various siloxane polymers with reactive functional groups, used as organosilicon copolymerization modification of organic polymers. It can also be used as a reducing agent in organic synthesis.
1,1,3,3-Tetramethyldisiloxane is volatile and flammable. When using it, keep it away from fire and heat sources and maintain a well-ventilated environment.
Avoid contact with strong oxidants, strong acids, strong alkalis and other substances to avoid chemical reactions.
It is irritating to the skin and eyes. When operating, you should wear appropriate protective equipment, such as gloves, goggles, etc. If it comes into contact with the skin or eyes accidentally, rinse immediately with plenty of water and seek medical attention in time.
