Why Silane Coupling Agents Are Used

With silane, the epoxy coating on the silica particles is apparent; without silane, clean silica particles can be seen in the epoxy matrix.

What is silane coupling agent used for?

One of the applicable properties of silane is its ability to form strong chemical bonds with other materials. This makes it an excellent choice for use as an adhesive or sealant because it can form strong bonds with a wide variety of substrates, including metals, plastics, glass, ceramics, and even wood.

Silanes and Silicones for Epoxy Resins

Silane coupling agents find applications as adhesion promoters for composites and coatings. Silanes have the ability to form covalent bonds with inorganic substrates and epoxy resins. Most commonly, epoxycyclohexyl- and glycidoxy-functional silanes are used to pretreat fillers or are blended with the epoxy resin.

The interface can be dramatically enhanced with a coupling agent

Silane coupling agents, which are synthetic hybrid inorganic-organic compounds, are used to promote adhesion between dissimilar materials.

How to Choose a Silane Coupling Agent

All silane coupling agents with three OR groups on silicon should bond equally well with an inorganic substrate. Our brand product line includes a variety of organofunctional alkoxysilanes.
