Description

n-(10,10-Dimethoxy-11-Oxa-3,6-Diaza-10-Siladodec-1-Yl)-N'-[2-[[3-(Trimethoxysilyl)Propyl]Amino]Ethyl]Ethane-1,2-Diammonium Dichloride is a high-purity, multi-functional organosilane quaternary ammonium compound. This advanced molecule is engineered to provide superior surface modification and adhesion promotion, particularly on challenging substrates. It is essential for formulators and manufacturers in industries requiring durable surface treatments, enhanced material compatibility, and antimicrobial functionality. Its unique structure combines silane coupling agents with quaternary ammonium groups to deliver multifunctional performance.

Application

• Surface Modification Agent: Used to functionalize inorganic surfaces like glass, silica, and metals to improve adhesion for coatings, sealants, and composites.
• Antimicrobial Coating Formulation: Serves as a key biocide component in paints, polymers, and textiles, providing durable antimicrobial properties.
• Adhesion Promoter: Enhances the bond strength between organic polymers (e.g., epoxies, acrylics) and inorganic substrates in high-performance adhesive systems.
• Fiber Treatment: Applied to glass or mineral fibers to improve resin wettability and interfacial strength in fiber-reinforced plastics (FRP).
• Paper and Textile Sizing: Imparts water repellency, softness, and antimicrobial characteristics to specialty papers and technical textiles.
• Cosmetic and Personal Care Additive: Used in hair conditioning and skin care products for its substantive and film-forming properties.
• Water Treatment: Acts as a flocculant and biocide in industrial water treatment processes.
• Research & Development: A valuable intermediate for synthesizing novel functional materials and studying surface chemistry.
