1,1,3,3-Tetramethyldisiloxane is used as a monomer in the production of silicone polymers or silicone resins. It is used as a precursor to prepare other organosilicon compounds. It is also utilized in non-aqueous polymer preparation as well as a laboratory reagent.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
1,1,3,3-Tetramethyldisiloxane is used as a monomer in the production of silicone polymers or silicone resins. It is used as a precursor to prepare other organosilicon compounds. It is also utilized in non-aqueous polymer preparation as well as a laboratory reagent.
Solubility
It reacts with water to produce dimethylsilanol, dimethylsilanediol and hydrogen gas.
Notes
Moisture sensitive. Keep away from sources of ignition. Store in cool place.
