二甲基十八烷基[3-(三甲氧基硅基)丙基]氯化铵 (CAS No.27668-52-6)

Product Name:Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride

English Name:Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride

CAS No.:27668-52-6

Aliases:Textile antibacterial agent, Textile fungicide, Eco-friendly high-efficiency antibacterial agent, Anti-mildew antibacterial agent

Molecular Formula:C26H58ClNO3Si

Physical Properties:Appearance is a light yellow to amber transparent liquid with a slight characteristic odor. It is readily soluble in water, ethanol, and isopropanol, and exhibits cationic character in water. Its density is approximately 0.98 g/cm³ (25°C). It has a flash point above 100°C, is non-flammable, and possesses good chemical stability. As an organosilicon quaternary ammonium salt, its molecule contains both a long-chain alkyl group and a hydrolyzable trimethoxysilyl group, endowing it with notable surface activity and reactivity.

Uses:It is used as an efficient antibacterial, germicidal, and anti-mildew finishing agent, widely applied in the antimicrobial treatment of textiles, nonwovens, shoe materials, furniture fabrics, and filter media. The trimethoxysilyl group in the molecule can form stable bonds with fiber surfaces, imparting durable and wash-resistant antibacterial and anti-mildew properties to fabrics while maintaining their original hand feel and breathability.
