Bifunctional silane coupling agent with epoxy and hydrolyzable methoxy groups for covalent bonding to both organic polymers and inorganic substrates.
Enhances adhesion, moisture resistance, and mechanical performance in filled composites and coating systems.
Offers excellent shelf stability in anhydrous conditions and controlled reactivity during processing.
Enables improved dispersion of fillers such as silica, glass fibers, and minerals in epoxy, acrylic, and polyester resins.
Compatible with common solvent-based and water-reducible formulations without significant gelation risk under proper handling.
Adhesion promoters in structural epoxy adhesives and automotive under-hood sealants.
Surface treatment for glass fibers and mineral fillers in thermoset composites (e.g., BMC, SMC).
Functional additive in UV-curable and thermally cured coatings for metals and plastics.
Performance enhancer in silicone-modified epoxy encapsulants and electrical potting compounds.
Interfacial modifier in hybrid sol-gel coatings and nanocomposite formulations.
