Description

Chlorotris(1,3-Dimethylbutoxy)Silane is a specialized organosilicon compound that serves as a versatile intermediate and coupling agent. Its molecular structure, featuring a reactive chlorosilane group and branched alkoxy ligands, makes it highly valuable for modifying surfaces and polymers to impart specific functional properties. This chemical is essential for manufacturers in the silicone, adhesive, sealant, and advanced material coating industries seeking to enhance product performance, adhesion, and durability.

Application

• Surface Treatment Agent: Used as a primer or adhesion promoter for coatings on glass, metals, and plastics.
• Silicone Intermediate: A key building block in the synthesis of modified silicone oils, resins, and elastomers.
• Crosslinking Agent: Employed in moisture-curable sealants, adhesives, and RTV (Room Temperature Vulcanizing) silicone formulations.
• Filler Treatment: Enhances the compatibility and dispersion of inorganic fillers (e.g., silica, calcium carbonate) in polymer matrices.
• Water Repellency: Imparts hydrophobic characteristics to construction materials, textiles, and stone.
• Polymer Modification: Used to introduce silane functionality into organic polymers for improved weather resistance and mechanical properties.

Quality Control

Our production of Chlorotris(1,3-Dimethylbutoxy)Silane adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) documenting purity, chloride content, and other critical parameters are provided with every shipment to support your quality assurance and regulatory needs.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
