Andisil® 6021 Silane is a bifunctional silane possessing a reactive amino groups and hydrolysable methoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. Glass, metals, fillers) and organic polymers (e.g. Thermoplastics, thermosets or elastomers).

Coupling agent in filled polymer systems, which cure via free radical mechanisms, copolymerization or grafting and as a surface modifier. Silanes are used in a variety of industrial applications. Organofunctional Silanes have an organic functional end group and an alkoxy functional end group which allow the silane to act as a bridge between organic materials and inorganic substrates. The organic functional group is matched to the resin system while the alkoxy group provides the reactive site for crosslinking. These materials are useful as adhesion promoters, crosslinking agents, surface modifiers and hydrophobizing agents.
