Application and Usage

It is a clear and almost colorless fluid with a typical smell (MEKO). It is used as a neutral curing agent in silicone sealant formulations. In most cases, it is used in combination with methyloximesilane. 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.
