HENGDA-M3133 - 3-(2,3-Epoxypropoxy)propyltrimethoxysilane

KH-560
HENGDA-M3133

3-(2,3-Epoxypropoxy)propyltrimethoxysilane is an organosilane coupling agent that contains both an epoxy group (-O-CH₂-CH(OH)-CH₂-O-) and a trimethoxysilane group (-Si(OCH₃)₃) attached to a propyl chain (-CH₂CH₂CH₂).
Here are the key aspects of 3-(2,3-Epoxypropoxy)propyltrimethoxysilane:
Epoxypropoxy group (-O-CH₂-CH(OH)-CH₂-O-): Contains an epoxy functional group, which is reactive and capable of cross-linking with various substrates.
Propyl group (-CH₂CH₂CH₂): Serves as the main backbone for the molecule.
Trimethoxysilane group (-Si(OCH₃)₃): This group is hydrolysable, allowing it to bond strongly to inorganic surfaces.
