Silane Coupling Agent
Mercapto Silane
Mercapto silane is a silane coupling agent with mercapto functional groups, used as adhesion promoters, surface modifiers, coupling agents and crosslinkers. With the presence of mercapto group and alkoxy group, mercapto silane coupling agent can build a molecular bridge between organic resins and inorganic substrates.
