Description

Isopropyltrichlorosilane is a highly reactive organosilicon compound primarily used as a key intermediate in the synthesis of silicone polymers and as a versatile surface modifying agent. Its value lies in its ability to introduce hydrophobic, cross-linking, or adhesion-promoting properties to a wide range of inorganic and organic substrates. This chemical is essential for manufacturers and R&D facilities in the semiconductor, specialty coatings, adhesives, and advanced materials sectors.

Application

• Silicone Intermediate: A crucial monomer for the production of modified silicone oils, resins, and elastomers.
• Surface Treatment Agent: Used to hydrophobize and functionalize surfaces of glass, silica, metals, and minerals to improve compatibility with organic matrices.
• Adhesion Promoter: Acts as a coupling agent in composite materials, enhancing the bond between inorganic fillers and organic polymer resins.
• Semiconductor Manufacturing: Employed in chemical vapor deposition (CVD) processes as a precursor for silicon-containing thin films and dielectric layers.
• Water Repellent Coatings: A key component in formulations for creating durable, water-resistant coatings on construction materials and textiles.
• Chemical Synthesis: Serves as a starting material or protecting group reagent in the synthesis of more complex organosilicon molecules.

Quality Control

Our Isopropyltrichlorosilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including gas chromatography (GC) for assay and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials such as strong bases, alcohols, and water. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C for extended stability.
