Methacryloxy functional silane with isopropenoxy (acetone-releasing) leaving groups instead of the more common alkoxy or oxime groups. Cures on exposure to atmospheric moisture, releasing acetone rather than alcohol, ketoxime or acetic acid, while the methacrylate group copolymerizes with acrylic and vinyl monomers — a low-odor, non-corrosive crosslinker for sealants and coatings.
