Description

Dodecyldimethyl[3-(Triethoxysilyl)Propyl]Ammonium Chloride is a versatile organosilane quaternary ammonium compound that combines the durable bonding properties of a silane with the potent antimicrobial and surfactant characteristics of a quat. This dual functionality makes it a critical additive for creating long-lasting, surface-bound active properties. It is essential for manufacturers in the coatings, textiles, and plastics industries seeking to impart permanent antimicrobial, antistatic, or surface-modifying features to their products. The compound's reactive triethoxysilyl group enables covalent bonding to inorganic substrates, while the cationic ammonium moiety provides excellent biocidal and surface-active performance.

Application

• Antimicrobial Coatings and Finishes: Used to create durable, non-leaching antimicrobial surfaces on textiles, plastics, glass, and metals for medical devices, HVAC filters, and high-touch surfaces.
• Surface Modification Agent: Imparts permanent hydrophilicity, antistatic properties, or improved adhesion to inorganic materials like glass, silica, and metals.
• Fiber and Fabric Treatment: Provides durable antimicrobial and softening finishes for synthetic and natural fibers in technical textiles and apparel.
• Resin and Polymer Additive: Incorporated into polymer matrices (e.g., silicones, epoxies) to enhance surface characteristics and provide built-in antimicrobial protection.
• Cosmetic and Personal Care Preservative: Acts as a conditioning agent and preservative in formulations where substantive, surface-bound activity is desired.
• Water Treatment and Filtration Media: Used to functionalize filter media to prevent biofilm formation and improve filtration efficiency.
