Colorless or yellowish transparent liquid
2, 4, 6, 8-TETRAMETHYLCYCLOTETRASILOXANE can be used as the precursor for the deposition of polysiloxane, cyclic siloxane, silicon dioxide, and gate dielectrics in thin-film transistors (TFT) (for example, for the preparation of ultralow dielectric constant pSiCOH film), and is a component of photochemically formed SiOX monolayers on TiO. It is a good impregnant of photoelectric material. It can be used for the manufacturing of modified siloxane with defined hydrogen content and chain quality.
2,4,6,8-Tetramethylcyclotetrasiloxane can occur addition reaction with unsaturated alkenes, so it’s utilized widely to synthesize variety functional reactive silicone fluids which is used to form silicone block copolymer, or used as crosslinker of vinyl addition silicone rubber.
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.
