OXIMINO SILANE CROSSLINKERS

Oxime silane based crosslinkers are used for producing neutral moisture-curing silicone sealants. Using these silane compounds, hydroxy-functionalized silicone polymers are crosslinked to obtain a silicone elastomer under the effect of a catalyst and moisture. When using oximino crosslinkers, no acetic acid or amine is released in contrast to acid or alkaline crosslinking systems, but 2-butanone oxime. As this cleavage product reacts neutrally, sealing compounds based on oximino crosslinkers can be used even on sensitive substrates such as marble.
