Application

 (3-Glycidyloxypropyl)triethoxysilane is mainly used to improve the adhesion between the surface of organic material and inorganic material, for example, in the treatment of the glass fabric in glass steel and the silicon stuffing in plastic, rubber, paint, coating, etc. It is also used in adhesives to strengthen the adhesion. The suitable resins include epoxy, phenol aldehyde, melamine, polysulfide, polyamino ester, polystyrene, etc.

 (3-Glycidyloxypropyl)triethoxysilane improves the adhesion between inorganic stuffing, base material and resin, hence improves the mechanical strength, electric property of composite material and high retention in wet state.

As the surface treating agent of inorganic stuffing,  (3-Glycidyloxypropyl)triethoxysilane  is widely used in pottery clay, talcum powder, silicon grey clay, white carbon black, silica, aluminum powder, iron powder, etc.

 (3-Glycidyloxypropyl)triethoxysilane is used as epoxy sealing agent to stuff silica, epoxy concrete remedy material or coating to stuff sand and epoxy mould material to stuff metal.

 (3-Glycidyloxypropyl)triethoxysilane can also improve the adhesion of double-component epoxy sealing agent, acrylic acid latex, sealing agent, polyamino ester and epoxy coating.
