Description

Dimethyl[2-[(2-Methyl-1-Oxoallyl)Oxy]Ethyl][3-(Trimethoxysilyl)Propyl]Ammonium Bromide is a specialized organosilicon quaternary ammonium compound, engineered to provide durable antimicrobial and surface-modifying properties. This advanced molecule is critical for formulators seeking to create long-lasting, non-leaching biocidal activity on a wide range of substrates. It is primarily utilized in the development of high-performance coatings, advanced textiles, and specialty polymers where permanent hygiene and surface functionality are required.

Application

• Antimicrobial Coatings and Paints: As a key functional additive for creating durable, non-migrating antimicrobial surfaces on walls, medical equipment, and high-touch surfaces.
• Functional Textile Finishing: For imparting permanent antibacterial, antifungal, and odor-resistant properties to fabrics, nonwovens, and technical textiles.
• Medical Device Polymers: Incorporated into polymer matrices for catheters, wound dressings, and other devices to prevent biofilm formation and microbial colonization.
• Advanced Adhesives and Sealants: To provide built-in antimicrobial protection and improved adhesion to various inorganic substrates via its silane functionality.
• Surface Modification of Fillers: Used as a coupling agent to treat silica, glass, and other mineral fillers, enhancing their compatibility with polymer matrices and imparting antimicrobial activity.
• Water Treatment Systems: For functionalizing filter media and membranes to prevent biofouling and bacterial growth.

Quality Control

Our production of Dimethyl[2-[(2-Methyl-1-Oxoallyl)Oxy]Ethyl][3-(Trimethoxysilyl)Propyl]Ammonium Bromide adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and assay, NMR for structural confirmation, and Karl Fischer titration for moisture content. Certificates of Analysis (COA) detailing all specifications are provided with each shipment to ensure traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials such as strong acids and bases.
