Description

Tetradecyldimethyl(3-Trimethoxysilylpropyl)Ammonium Chloride is a quaternary ammonium silane, a versatile organofunctional compound that combines the antimicrobial properties of a quat with the durable bonding capability of a silane. This dual functionality makes it a critical component for creating long-lasting, hygienic surfaces and materials. It is primarily used by formulators in the coatings, plastics, textiles, and construction industries seeking to impart permanent antimicrobial and surface-modifying properties to their products.

Application

• As a durable antimicrobial agent in paints, coatings, and sealants for hospitals, food processing facilities, and public spaces.
• As a surface modifier and coupling agent to improve adhesion between organic polymers and inorganic substrates like glass, metals, or minerals.
• In the production of antimicrobial textiles and nonwovens for medical fabrics, sportswear, and filtration media.
• For functionalizing fillers and pigments (e.g., silica, titanium dioxide) to enhance dispersion and compatibility in polymer matrices.
• In the formulation of specialty hair conditioners and personal care products where substantive conditioning is required.
• As an additive for advanced composite materials to improve interfacial strength and material performance.
