HENGDA-E2133 - 3-Methacryloxypropyltriethoxysilane

3-Methacryloxypropyltriethoxysilane is an organosilane coupling agent that comprises a methacryloxypropyl group attached to a triethoxysilane group.
Chemical Structure:
Methacryloxypropyl Group (-CH2=CHC(O)OCH2CH2CH2Si(OC2H5)3): Provides reactive vinyl functionality for crosslinking and polymerization.
Triethoxysilane Group (-Si(OC2H5)3): Hydrolysable group for adhesion to inorganic surfaces by forming silanol bonds.

  • Chemical Name:

    3-Methacryloxypropyltriethoxysilane

  • CAS No.

    21142-29-0

  • Equivalent Name:

    Y-11878

Applications

  1. Coupling Agent: It is widely used as a coupling agent and adhesion promoter in various industries, particularly in coatings, adhesives, and sealants.

  2. Surface Modifier: Improves the compatibility and bonding between organic polymers (such as acrylics, epoxies) and inorganic substrates (like glass, metals, ceramics).

  3. Polymer Modification: Used to functionalize polymers by introducing reactive groups that can participate in cross-linking reactions, improving mechanical properties.
