Applications

Silane USi-4VO is an essential coupling agent in industries as below :

  • Vinyltris(methylethylketoxime)silane is widely used as a cross-linker /coupling agent / accelerator / promotor for RTV (Room Temperature Vulcanizing) silicone rubber and silicone sealant.
  • Used as a neutral curing agent in silicone sealant formulations
  • Used in combination with methyloxime silane. 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.
