Name: Generic D-26 Silane Coupling Agent 1,2-Bis(trimethoxysilyl)ethane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Generic D-26 Silane Coupling Agent 1,2-Bis(trimethoxysilyl)ethane

Bifunctional silane with two hydrolyzable trimethoxy groups per molecule, enabling robust covalent bridging between organic polymers and inorganic substrates.
Ethylene bridge provides enhanced hydrolytic stability compared to shorter-chain analogues, reducing premature condensation during storage and processing.
Low volatility and favorable handling characteristics due to its liquid form and moderate molecular weight (348.5 g/mol).
Excellent compatibility with epoxy, phenolic, and polyurethane resin systems without significant viscosity build-up.
Enables improved interfacial adhesion, moisture resistance, and mechanical durability in filled composites and coatings.

Typical Applications Of Generic D-26 Silane Coupling Agent 1,2-Bis(trimethoxysilyl)ethane

Surface modification of silica, glass fibers, and mineral fillers in high-performance thermoset composites.
Adhesion promoter in automotive and aerospace structural adhesives and sealants.
Moisture-cure additive for silicone-modified alkyd and hybrid resin coatings.
Reinforcement aid in rubber compounds containing siliceous fillers (e.g., tire treads and industrial rubber goods).
Functional crosslinker in sol-gel derived hybrid organic-inorganic coatings and encapsulants.
