Description

Silane, Chlorobis(1-Methylethyl)(Octyloxy)- CAS NO 184719-55-9 is a specialized organosilicon compound featuring a reactive chlorosilane group and a long-chain alkoxy substituent. This unique structure makes it a valuable intermediate for introducing hydrophobic and organofunctional properties into materials. It is primarily sought after by manufacturers in the silicone polymer, surface treatment, and advanced materials sectors for its role as a coupling agent and precursor.

Application

• As a key coupling agent in the synthesis of modified silicones and siloxane polymers.
• Surface modification of inorganic fillers (e.g., silica, minerals) to improve dispersion and compatibility in polymer matrices.
• Hydrophobic treatment agent for construction materials, textiles, and paper to impart water repellency.
• Intermediate in the production of specialty silane adhesion promoters for sealants, adhesives, and coatings.
• Precursor for synthesizing other functional silanes used in release coatings and mold-making applications.
• Component in formulations for protecting sensitive electronic components from moisture.

Quality Control

Our production of Chlorobis(1-Methylethyl)(Octyloxy)silane adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis, including assay, purity verification, and identity confirmation. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain purity. Keep away from strong acids and incompatible materials.
