Description

n-Trimethoxysilylpropyl-N,N,n-Tri-n-Butylammonium Chloride: 50% In Methanol is a quaternary ammonium functional silane coupling agent supplied as a 50% solution in methanol. This unique bifunctional molecule is engineered to provide durable antimicrobial and surface-modifying properties by chemically bonding to inorganic substrates. It is a critical raw material for manufacturers in the coatings, textiles, and plastics industries seeking to impart long-lasting biocidal activity and improved adhesion. The solution format ensures ease of handling and integration into various formulation processes.

Application

• Antimicrobial Coatings and Paints: Used as a functional additive to create durable, non-leaching antimicrobial surfaces on walls, medical equipment, and high-touch public areas.
• Functional Textile Finishing: Imparts permanent antibacterial and antifungal properties to natural and synthetic fibers for medical textiles, sportswear, and upholstery.
• Plastics and Polymer Modification: Incorporated into polymer matrices to develop antimicrobial masterbatches for consumer goods, packaging, and healthcare products.
• Surface Pretreatment for Adhesion Promotion: Acts as a coupling agent on glass, metal, and mineral surfaces to enhance the bonding of subsequent polymer layers or coatings.
• Water Treatment and Filtration Media: Used to functionalize filter membranes and media to prevent biofilm formation and microbial growth.
• Personal Care and Hygiene Products: Employed in formulations where long-lasting antimicrobial efficacy on surfaces is required.

Quality Control

Our n-Trimethoxysilylpropyl-N,N,n-Tri-n-Butylammonium Chloride 50% solution is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, concentration, and performance. Key parameters including assay, solvent content, and identity are verified. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed when not in use to prevent moisture absorption and solvent evaporation. Keep away from heat, sparks, and open flame.
