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.
