Highly reactive diamino-functional silicone backbone enables strong covalent bonding with substrates including polyurethanes, epoxies, and acrylics.
Low viscosity liquid form ensures excellent processability in mixing, coating, and impregnation operations without solvent dilution.
Enhances adhesion, flexibility, and hydrolytic stability in crosslinked polymer systems, especially under humid or elevated-temperature conditions.
Offers superior compatibility with both organic resins and inorganic fillers, minimizing phase separation in formulated systems.
Free of heavy metals and REACH-compliant, supporting sustainable manufacturing and regulatory alignment for global markets.
Adhesion promoters in automotive sealants and structural adhesives.
Surface modifiers for glass fiber sizing in composite reinforcements.
Functional additives in high-performance polyurethane coatings for industrial maintenance.
Compatibilizers in silicone-modified epoxy encapsulants for electronics protection.
Reactive intermediates in the synthesis of silicone-acrylate hybrid emulsions for architectural coatings.
