Product Description

1. Long-Acting Antibacterial & Mildew-Proof Functional Coating Precursor

N-[3-(Trimethoxysilyl)propyl]-N,N,N-trimethylammonium chloride is a typical cationic organosilicon quaternary ammonium salt monomer with dual functional groups of hydrolyzable trimethoxysilyl and positively charged quaternary ammonium salt. After hydrolysis and crosslinking, the monomer can be firmly anchored on the material surface, and the positively charged quaternary ammonium group can efficiently adsorb and destroy the cell membrane structure of bacteria and fungi, achieving efficient and broad-spectrum antibacterial and bacteriostatic effects. Different from traditional physically blended antibacterial agents, it is covalently bonded to the substrate without migration, precipitation or failure, and has lasting antibacterial durability. It is widely used in the preparation of antibacterial coatings, mildew-proof protective films and sanitary functional materials for public facilities and medical environments.

2. Water-Based System Interface Compatibility & Polar Modification Agent

Benefiting from the strong hydrophilicity and high polarity of quaternary ammonium cationic groups, this silane monomer has excellent water solubility and water-based system compatibility. It can be uniformly dispersed and stably copolymerized in water-based emulsions, water-based resins and aqueous coating systems without organic solvent participation. It effectively improves the surface polarity, wettability and interfacial bonding force of water-based materials, solves the problems of poor dispersion, easy delamination and low adhesion of conventional hydrophobic silane monomers in water-based systems, and significantly enhances the film-forming compactness and mechanical stability of water-based functional coatings.

3. Inorganic Filler Surface Activation & Dispersion Modifier

This cationic silane modifier can perform surface activation and charge regulation on inorganic fillers such as silica powder, talc powder, clay and glass fiber. The trimethoxysilyl group is covalently bonded to the hydroxyl groups on the filler surface to achieve stable coating modification, while the positively charged quaternary ammonium group changes the surface charge characteristics of the filler, effectively inhibiting particle agglomeration and improving uniform dispersion in polymer matrices. It optimizes the interfacial compatibility between inorganic fillers and organic resins, reduces interface defects, and improves the mechanical strength, weather resistance and comprehensive service performance of composite materials.

4. Anti-Static & Dust-Proof Functional Material Intermediate

The permanently charged quaternary ammonium cationic structure endows the modified material with stable surface conductivity and electrostatic dissipation performance, which can effectively eliminate static charge accumulation on the surface of polymer films, plastic materials and optical devices. It solves the problem of easy dust adsorption and static damage caused by high insulation of traditional polymer materials. Combined with the dense crosslinked siloxane network, it achieves dual effects of static resistance and dust adhesion inhibition, and is suitable for the preparation of anti-static packaging materials, electronic device protective coatings, dust-proof functional films and indoor durable protective materials.
