Silane coupling agents methacryl functional

Many other functional silane coupling agents are available from commercial suppliers, including hydroxyl, aldehyde, acrylate and methacrylate, and anhydride compounds. Substrate modification procedures similar to those discussed above can be used with these reagents to link a biomolecule to an inorganic surface or particle. 

Adhesion promoter chemistries, other than those of silanes, have been extensively evaluated for many years. These materials use the same concepts as silane-coupling agents, but they are based on other metallic elements. They have inorganic reactivity on the metallic atom and contain organofunctional groups, such as methacrylate, carboxylate, and others, with dual- or multi-functionality built into the...

Chloropropyl, vinyl, and methacrylate-functional silanes on glass were only slightly better than untreated surface for adhesion to most of the rubbers. The mercaptan and amine-functional silanes have been the preferred silanes on fillers in sulfur-vulcanized rubbers. The amine gave better adhesion to natural, nitrile, and Hypalon rubbers, while the mercaptan was better with SBR, Neoprene and EPDM. The iso-thiuronium-functional silane appears to be fairly effective in bonding all rubbers—but especially SBR. Anionic or cationic styryl coupling agents were the best unsaturated silanes and contributed true adhesion to EPDM and Hypalon.
