Description

Silane, Chlorohexadecyldimethyl- is a long-chain alkylchlorosilane monomer, a key organosilicon intermediate for introducing hydrophobic and self-assembling properties to surfaces. Its value lies in its ability to form durable, covalently bonded monolayers on hydroxylated substrates like glass, silica, and metals, significantly altering surface energy and functionality. This product is essential for manufacturers and R&D teams in the advanced materials, specialty coatings, and nanotechnology sectors seeking to engineer surfaces with specific wettability, adhesion, or release characteristics.

Application

• Surface modification agent for creating hydrophobic and oleophobic coatings on glass, quartz, and optical fibers.
• Key precursor for synthesizing functionalized silica nanoparticles and other inorganic-organic hybrid materials.
• Coupling agent and adhesion promoter in specialty polymer composites and sealants.
• Formation of self-assembled monolayers (SAMs) for research in nanotechnology, biosensors, and microelectromechanical systems (MEMS).
• Water repellent treatment for textiles, ceramics, and construction materials.
• Intermediate in the production of quaternary ammonium silanes for antimicrobial surface treatments.

Quality Control

Our Chlorohexadecyldimethylsilane is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure high chemical purity and identity confirmation. We provide detailed Certificates of Analysis (COA) with every shipment, documenting all critical parameters to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its moisture-sensitive (hygroscopic) nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature: 2-8°C for long-term stability.
