VANABIO® AS1208

Application


  • This organic 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 silane 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 and Storage


  • VANABIO® AS1208 is supplied in 200Kg steel drum or 1000Kg IBC container.


  • In the unopened original container VANABIO® AS1208 has a shelf life of one year in a dry and cool place.
