Product Overview
Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride is a high-purity silane quaternary ammonium compound supplied as a 60% solution in methanol. This organosilane features a trimethoxysilyl group for covalent bonding to inorganic surfaces and a quaternary ammonium moiety that provides long-lasting antimicrobial properties. The methanol solvent ensures uniform dispersion and reactivity during application. Its dual functionality makes it particularly effective for modifying glass, metal, and ceramic substrates to inhibit microbial growth. The compound’s hydrophobic long-chain alkyl group enhances durability while maintaining compatibility with aqueous and solvent-based systems. With a molecular structure designed for both adhesion and biocidal activity, this reagent is a critical component in formulations requiring persistent antimicrobial performance without leaching. The laboratory-grade purity ensures consistent results in research and development applications where surface chemistry precision is paramount.
FAQs
1. What type of surfaces can this silane quat effectively bond to?
It forms strong covalent bonds with hydroxylated surfaces like glass, silica, metals, and most ceramics through its trimethoxysilyl groups.
2. Is this product compatible with water-based coating systems?
The methanol solution allows for initial compatibility, but the silane requires hydrolysis in aqueous systems before forming stable bonds with substrates.
3. What’s the shelf life when stored unopened at room temperature?
When kept in its original sealed container away from moisture, the product maintains stability for 12 months from the date of manufacture.
4. Can this be used as a direct replacement for traditional quaternary ammonium sanitizers?
Unlike temporary sanitizers, this silane quat chemically bonds to surfaces, providing persistent antimicrobial activity rather than short-term disinfection.
5. What safety precautions are essential when handling the methanol solution?
Use in a well-ventilated area with proper PPE, as methanol is flammable and the solution may release methanol vapors during application.
