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 SILICONES provides 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 products like 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.
