GENIOSIL® XL 33

Methacryloxymethyltrimethoxysilane by Wacker is a moisture scavenger and crosslinker with a characteristically sweet odor. GENIOSIL® XL 33 is an organofunctional silane that hydrolyzes in the presence of moisture (methanol is released) to form silanols, which can then react with themselves to produce siloxanes or bind to inorganic substrates.

• The close proximity of the alkoxysilyl group to the ester function results in greatly accelerated hydrolysis and condensation reactions (alpha-effect).
• It can thus function as a molecular bridge between inorganic and organic substrates.
• Designed for heat and/or radiation-curable adhesives and sealants.
• It is organically unsaturated molecule, it can be incorporated into organic polymers by radical grafting, and bond to inorganic substrates by alkoxysilyl group.
