SiSiB® PC7500 Vinyltris(methylethylketoxime)silane
SiSiB® PC7500
Vinyl tris methylethylketoxime silane
SiSiB® PC7500 (VOS silane) is used as a neutral curing agent in silicone sealant formulations. Generally, this silane is used for crosslinking α,ω-silanol polydimethylsiloxanes in the presence of atmospheric moisture.
SiSiB® PC7500 silane is the equivalent of Evonik's OX 20 and Nitrochemie's OS 2000.

Application
SiSiB® PC7500 vinyl tris methylethylketoximino silane is used as a neutral curing agent in silicone sealant formulations.
In most cases SiSiB® PC7500 vinyl tris (butanone oxime) silane is used in combination with MOS silane (SiSiB® PC7130). Compared to formulations based on methyloxime silanes only, the use of combinations containing methyl- and vinyloxime silanes leads to a shorter skin formation time of the silicone sealant without a reduction of the curing time. The ability of the sealant to withstand stress early, required for a certain elasticity and tear resistance, is achieved.
Packing and Storage
SiSiB® PC7500 clear silicone sealant is supplied in 200Kg steel drum or 950Kg IBC container.
In the unopened original container SiSiB® PC7500 has a shelf life of one year in a dry and cool place.
