Highly reactive alkoxy-silane functionalized with methacryloxy groups for robust 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.
Offers excellent hydrolytic stability in formulated systems due to optimized alkoxy group balance (methoxy/ethoxy).
Designed for low-volatility processing with minimal odor and reduced VOC contribution versus traditional silanes.
Compatible with free-radical polymerization processes, supporting use in UV-curable and thermally cured coatings and composites.
Adhesion promoters in automotive clearcoats and primerless coating systems.
Surface modifiers for glass fiber reinforcements in thermoset composites (e.g., BMC, SMC).
Functional additives in high-performance sealants and structural adhesives.
Interfacial coupling agents in mineral-filled polypropylene and engineering thermoplastics.
Enhancement of pigment dispersion and binder-substrate bonding in industrial coil coatings.
