Tri-functional silane coupling agent with three hydrolyzable methoxy groups for robust covalent bonding to inorganic surfaces.
Contains a highly reactive diethylenetriamine (DETA) moiety, enabling strong interaction with epoxy, polyurethane, and acrylic resins.
Enhances interfacial adhesion between organic polymers and fillers such as silica, glass, or metals in composite formulations.
Improves moisture resistance and long-term durability of coatings, adhesives, and sealants exposed to humid or corrosive environments.
Enables efficient surface modification of nanoparticles and functionalized pigments for improved dispersion stability.
Adhesion promoters in structural adhesives and automotive bonding systems.
Surface modifiers for silica-based reinforcing fillers in high-performance rubber compounds.
Functional additives in epoxy-based composites for aerospace and wind energy applications.
Hybrid sol-gel precursors for corrosion-inhibiting primers on aluminum and steel substrates.
Dispersion aids for metal oxide nanoparticles in conductive inks and functional coatings.
