Methylvinylbis(methylisobutylketoxime)silane

Oxime functional silane crosslinker for neutral-cure one-component silicone sealants and adhesives. Non-corrosive to metals and compatible with a wide range of substrates, including concrete and marble where acetoxy systems cannot be used. Difunctional methylvinyl silane carrying the bulkier methylisobutylketoxime leaving group, which slows hydrolysis for a longer working time than the MEKO analogue, with the vinyl group giving faster cure and better adhesion to plastics than the methyl-only grades.
