Name: Evonik Dynasylan GLYMO Trimethoxy(3-glycidyloxypropyl)silane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Evonik Dynasylan GLYMO Trimethoxy(3-glycidyloxypropyl)silane

Bifunctional silane coupling agent with epoxy (glycidyl) and hydrolysable methoxy groups for covalent bonding to both organic polymers and inorganic substrates.
Enables improved adhesion, dispersion, and interfacial compatibility in filled composites and hybrid systems.
Hydrolytically stable under controlled conditions; forms reactive silanol intermediates that condense with surface hydroxyls on glass, metals, or minerals.
Compatible with epoxy, phenolic, polyester, and acrylic resin systems—ideal for thermoset matrix modification.
Low volatility and favorable handling characteristics compared to chlorosilane alternatives, supporting safer industrial processing.

Typical Applications Of Evonik Dynasylan GLYMO Trimethoxy(3-glycidyloxypropyl)silane

Surface treatment of silica, glass fibers, and mineral fillers in epoxy-based composites for aerospace and automotive components.
Adhesion promoter in structural adhesives and sealants for metal-to-polymer or glass-to-resin bonding.
Functional additive in UV-curable coatings and inks to enhance substrate wetting and crosslink density at interfaces.
Modifier for sol-gel derived hybrid coatings providing corrosion resistance on aluminum and steel substrates.
