Highly reactive alkoxy-silane functionalized with methacryloxy group for covalent bonding to acrylic, polyester, and epoxy resins.
Enables superior adhesion promotion between organic polymers and inorganic substrates such as glass, metals, and mineral fillers.
Hydrolytically stable in anhydrous conditions, offering extended shelf life and consistent performance in solvent-based systems.
Low volatility and favorable handling characteristics compared to chlorosilanes, supporting safer industrial processing.
Designed for ambient-cure and thermal-cure formulations, providing flexibility across coating, adhesive, and composite manufacturing processes.
Adhesion promoters in automotive clearcoats and OEM primers.
Surface modifiers for glass fiber reinforcements in thermoset composites.
Functional additives in UV-curable and high-solids industrial coatings.
Performance enhancers in structural adhesives and sealants for construction and transportation.
Compatibilizers in filled polymer systems requiring improved dispersion and interfacial strength.
