SiSiB® PC7960 Vinyltriacetoxysilane

SiSiB® PC7960

Vinyltriacetoxysilane

SiSiB® PC7960 is a clear to yellowish liquid with acrid odor of acetic acid (vinegar). It hydrolyzes in the presence of moisture (acetic acid is released) to form silanols, which can react with themselves to pro-duce siloxanes or bind to inorganic substrates.

SiSiB® PC7960 is the equivalent of Dow's Z-6075, Wacker's GENIOSIL GF 62.

Application

SiSiB® PC7960 vinyltriacetoxysilane, VTAS silane, is used as a raw material (crosslinker) for acetoxy crosslinking RTV-1 sealants.

Acetoxy silanes are more reactive than alkoxy silanes. Acetoxy silanes are frequently used as one-component mixtures to make RTV-1 silicone sealants. These mixtures have an excess of multi-functional acetoxy silane added to silanol-terminated PDMS, which results in a PDMS chain with acetoxy groups at the ends.

When this compound is exposed to moisture some acetoxy groups are hydrolyzed and self-condense or react with other acetoxy and rapid crosslinking takes place. Acetic acid formation is one of the driving forces of this reaction.

SiSiB SILICONESprovides a comprehensive range of performance-enhancing products and solutions to better meet the need of customers. As a reliable company in China, SiSiB supplies custom silicone productslike silanes and siliconates, silicone fluids, silicone emulsion, silicone gel and oil, silicone polymer, silicone rubbers, silicone resins and fumed silicas, all manufactured by our factory.
