Description

2-Methacryloxyethyldimethyl(3-Trimethoxysilylpropyl)Ammonium Chloride is a highly versatile, dual-functional organosilane monomer featuring both a polymerizable methacrylate group and a cationic quaternary ammonium moiety. This unique structure makes it a critical component for imparting permanent antimicrobial, adhesive, and surface-modifying properties to a wide range of polymeric materials. It is essential for formulators and manufacturers seeking to develop advanced, high-performance coatings, adhesives, and composites with enhanced functionality and durability. The compound is identified by CAS No. 31681-13-7.

Application

• Antimicrobial Coatings and Films: As a key ingredient in the synthesis of polymers for medical devices, hospital surfaces, textiles, and food packaging to provide long-lasting antibacterial and antifungal properties.
• Dental and Biomedical Adhesives: Used to formulate primers and bonding agents that improve adhesion to tooth enamel, dentin, and various substrates while offering a bioactive, antimicrobial interface.
• Surface Modification of Fillers and Fibers: Employed as a coupling agent to treat glass, silica, and other mineral fillers, enhancing their dispersion in polymer matrices and improving composite mechanical strength.
• Quaternary Silane for Hair and Personal Care: Incorporated into conditioning agents and treatments for hair and skin to deliver substantive conditioning and antimicrobial benefits.
• Paper and Textile Treatment: Used to create durable, cationic finishes that provide softness, water repellency, and antimicrobial activity to fibers and nonwovens.
• Antifogging and Antistatic Coatings: A building block for polymers applied to optical lenses, mirrors, and electronic displays to prevent fogging and reduce static charge.

Quality Control

Our production of 2-Methacryloxyethyldimethyl(3-Trimethoxysilylpropyl)Ammonium Chloride adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, impurity profiling, and functional group verification, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) documenting purity, identity, and key physical-chemical parameters are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and stability. This product is hygroscopic (moisture-sensitive) and should be handled under a dry atmosphere to prevent hydrolysis and degradation of the silane functionality. Keep away from heat and incompatible materials.
