3-Methacryloxypropyltrimethoxysilane

The silane 3-methacryloxypropyltrimethoxysilane is one of the oldest and still one of the most important coupling agents available for improving the practical adhesion of polymers to minerals. It has also featured strongly in research and development studies establishing the dominance of the chemical bonding theory as the primary mechanistic explanation of silane coupling agent effectiveness. This aspect of 3-methacryloxypropyltrimethoxysilane studies is summarized in this review. Its surface energy and water wettability are also discussed and compared with those of related polymers. These physical properties ought to be of some importance in adhesion enhancement but evidently they are less significant than the chemical reactivity of the silane.
