Description

N,n-Didecyl-n-Methyl-n-(3-Trimethoxysilylpropyl)Ammonium Chloride is a quaternary ammonium silane, a bifunctional molecule that combines the potent antimicrobial properties of a quat with the durable, covalent bonding capability of a silane. This dual functionality makes it a critical component for creating long-lasting, non-leaching antimicrobial and surface-modifying treatments. It is essential for manufacturers in the coatings, textiles, plastics, and construction materials industries seeking to develop products with built-in, durable hygienic properties and improved adhesion.

Application

• Antimicrobial Coatings and Paints: Covalently bonds to surfaces to provide durable, non-leaching antimicrobial protection for high-touch surfaces in healthcare, food processing, and public spaces.
• Functional Textiles and Nonwovens: Imparts durable antimicrobial and antifungal properties to medical textiles, protective apparel, and technical fabrics.
• Surface Modification of Fillers and Pigments: Acts as a coupling agent to improve the dispersion and adhesion of inorganic fillers (e.g., silica, glass) in polymer matrices like plastics and sealants.
• Adhesion Promoters: Enhances the bonding of coatings, adhesives, and inks to difficult substrates such as glass, metals, and certain plastics.
• Construction Materials: Used in formulations for antimicrobial grouts, sealants, and concrete additives to inhibit mold and mildew growth.
• Personal Care and Cosmetics: Employed as a conditioning agent and preservative booster in formulations requiring substantive, long-lasting effects on hair or skin.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Each lot is characterized using advanced analytical techniques to confirm identity, purity, and functional group integrity. Certificates of Analysis (COA) detailing key specifications are available upon request. We adhere to a quality management system to support our global customer base.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture.
