Application and Usage

It is a clear colorless fluid with a typical smell (MEKO). It is oxime silane-based crosslinkers for producing neutral moisture-curing silicone sealants. Using these silane compounds, hydroxyl-functionalized silicone polymers are crosslinked to obtain a silicone elastomer under the effect of a catalyst and moisture. While using, no acetic acid or amine is released in contrast to acid or alkaline cross- linking systems, but methyl ethylketoxime. As this cleavage product reacts neutrally, sealing compounds based on crosslinker oxime can be used even on sensitive substrates such as marble. It is often the main crosslinker of choice for oxime silicone sealants and can be used by itself or in combination with other oximesilanes to provide the sealant with targeted properties (such as desired cure rate, adhesion, etc).
