Description

This Thermo Scientific 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.

Applications
It is employed as silylating agent for diols. Used as a monomer (‘building block’) in the production of silicone polymers or silicone resins, as an intermediate (starting material) in the production of other organosilicon substances. Also employed in non-metal surface treatment to enhance the adhesion properties of surfaces. Used in sealants, in silicone polymer preparations (for the production of elastomers), in mould-making, in semiconductor manufacture, as a laboratory chemical in research and development activities.

Solubility
Contact with water releases a flammable alcohol.

Notes
Moisture Sensitive. Store away from oxidizing agents and water/moisture. Protect against electrostatic charges. Keep ignition sources away.
