Description

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. Trifunctional vinyl silane carrying the standard methylethylketoxime (MEKO) leaving group — balanced cure speed and good storage stability, with more crosslink sites per molecule and faster cure and better adhesion to plastics than the methyl-only grades.
