Product Description

CFS-889 1,3,5,7-Tetramethylcyclotetrasiloxane Cas 2370-88-9 can occur addition reaction with unsaturated alkenes, so it's utilized widely to synthesize variety functional reactive siliconefluids 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.

Application:

 

Used as an adhesion promoter in coating and sealants.
Used as an additive for functional silicones synthesis.
Used in cosmetics, soaps, deodorant and food additives.

 

storage:
Stored in a cool, well-ventilated place, and avoid exposure to humidity.
Should be stored in its original containers and used up asap after opening.
The expected shelf life is 12months, when stored in a strictly sealed container and under proper conditions.

Packing & Delivery

CFS-889 is available in 25L PE pails, 200L steel drums or 1000L IBC totes.
Not hazardous goods.
