Vinyltriacetoxysilane Description

CFS-089, Vinyltriacetoxysilane is an acetoxy silane which is more reactive than alkoxysilanes. It is mainly used as a crosslinker for moisture curing RTV silicone rubbers. CFS-089 can be abbreviated as VTAS and treated as the equivalent of Dow Corning Z-6075.

Vinyltriacetoxysilane Application

CFS-089 is an important crosslinker for RTV silicone rubbers. It has faster moisture curing rate and better adhesion than CFS-343, Methyltriacethoxysilane.
CFS-089 can be also used as a coupling agent, an adhesion promoter in the synthesis of various organic silicone compounds.
CFS-089 can be used in micro and nanoparticle surface modification for inorganic fillers.

Vinyltriacetoxysilane Packaging

CFS-089 is offered in 25L PE pails, 200L PVF steel drums and 1000L IBC totes.
Please contact Co-Formula team for any special packaging request.

Vinyltriacetoxysilane Storage

CFS-089 should be stored in a cool, well-ventilated place, and avoid exposure to humidity.
CFS-089 should be stored in its original containers and used up as soon as possible after opening.
When stored in a strictly sealed and unopened container, CFS-089 has a shelf life of 12months.
