(3-Glycidoxypropyl)methyldiethoxysilane

(3-Glycidoxypropyl)methyldiethoxysilane (CAS 2897-60-1) is a bifunctional organosilane coupling agent carrying both an epoxy group and hydrolysable ethoxysilyl groups on the same molecule. It carries no assigned E-code or common trade abbreviation, and is classified under HS code 29319090 within the silicones and silicates category.

In adhesive and sealant formulations, the ethoxysilyl groups hydrolyse and condense onto inorganic substrates such as glass or metal oxides, while the epoxy group reacts with amine or anhydride curatives to form a covalent bridge between the organic polymer matrix and the substrate. In electronics encapsulants and protective coatings, this dual reactivity improves adhesion retention under humid or thermally stressed conditions.

This material is supplied as a neat liquid under REACH registration and is available in standard drum and IBC packaging suited to industrial procurement volumes. Buyers should confirm current SDS documentation and lot-specific purity certificates with the supplier prior to formulation use.
