Features Of Dow Corning Z-6040 Gamma-Glycidoxypropyltrimethoxysilane

  1. Bi-functional silane coupling agent with epoxy and hydrolyzable methoxy groups for covalent bonding to both organic polymers and inorganic substrates.

  2. Enhances adhesion, moisture resistance, and mechanical durability in composite systems and coated surfaces.

  3. Improves dispersion and interfacial compatibility of fillers (e.g., silica, glass fibers) in epoxy, polyester, and acrylic resins.

  4. Enables room-temperature or heat-assisted condensation reactions without requiring strong acid catalysts.

  5. Offers excellent shelf stability when stored under dry, cool conditions in sealed containers.

Typical Applications Of Dow Corning Z-6040 Gamma-Glycidoxypropyltrimethoxysilane

  1. Adhesion promoters in structural adhesives and sealants for automotive and aerospace assemblies.

  2. Surface treatment of glass fibers and mineral fillers in thermoset composites (e.g., epoxy, phenolic, unsaturated polyester).

  3. Primer component for coatings on metals, concrete, and ceramics to improve corrosion resistance and coating adhesion.

  4. Functional additive in UV-curable and thermally cured epoxy-based encapsulants and potting compounds.

  5. Modifier for hybrid sol-gel formulations used in protective and anti-graffiti coatings.
