Applications:

Triacetoxyethylsilane are more reactive than alkoxysilanes. Triacetoxyethylsilane are frequently used as one-component mixtures to make RTV-1 silicone sealants. These mixtures have an excess of multi-functional Triacetoxyethylsilane 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.

Packing:

Packed with 5L, 20L or 210L plastic/steel drum, 1000L IBC container, or according to customer’s requirement.
