Colorless clear liquid.

The Uses of (3-Glycidoxypropyl)methyldiethoxysilane

(3-Glycidyloxypropyl)methyldiethoxysilane is an organo-functional silane that can be used as a coupling agent between inorganic fillers (powdered silicas, glass, fiberglass, ceramics, etc.) and a wide variety of polymers such as epoxy, melamine, phenolic and urethane resins, polystyrene plastic, acrylic sealants, butyl rubber and water soluble polymers that contain hydroxyl groups and/or primary or secondary amine groups.

The Uses of (3-Glycidoxypropyl)methyldiethoxysilane

3-(Glycidoxypropyl)methyldiethoxysilane, silane coupling agent KH-7180, is a versatile epoxy organo-reactive silane with two hydrolyzable ethoxy groups. It provides shelf stable non-yellowing adhesion promoter performance while enhancing physical properties in latexes and waterborne adhesive and sealant systems.

The Uses of (3-Glycidoxypropyl)methyldiethoxysilane

GPMS can be used in the surface modification of a variety of particles such as cellulose nanocrystals, silica nanomaterials and other silicon based substrates. It functionalizes these surfaces by attaching the epoxy-silane groups with the surface molecules.

General Description

Diethoxy(3-glycidyloxypropyl)methylsilane (GPMS) is an epoxysilane which can be used as a silane coupling agent for the surface treatment of a variety of materials. These silanes can also be used as adhesion promoters by modifying the surface properties of the substrates and elastomeric materials.
