Description

Applications
Tetramethyl-cyclotetrasiloxane is a good impregnant of photoelectric material. It is used to manufacture of modified siloxane with defined hydrogen content and chain quantity. It is also used in production of silicone polymers and acts as a precursor for the deposition of polysiloxane, cyclic siloxane, silicon dioxide, oxycarbide thin films with low dielectric constant for microelectronics and semiconductors.

Solubility
Miscible with most organic solvents. Immiscible with water.

Notes
Incompatible with oxidizing agents, bases and acids. Store in a cool place.
