Description

Allyltrichlorosilane is a highly reactive organosilicon compound characterized by an allyl group bonded to a trichlorosilyl moiety. This unique structure makes it a versatile and essential intermediate for introducing the allyl functionality into silicon-based materials. It is primarily utilized in the synthesis of specialized silicone polymers, as a surface-modifying agent, and in the production of advanced adhesives and sealants.

Application

• Silicone Intermediate: A key precursor in the synthesis of functional silicone oils, resins, and elastomers with tailored properties.
• Surface Modification: Used as a coupling agent to modify inorganic surfaces (e.g., glass, silica) for improved adhesion with organic polymers.
• Adhesive & Sealant Formulation: Imparts cross-linking and adhesion-promoting characteristics in high-performance silicone-based adhesives and sealants.
• Chemical Synthesis: Serves as an allylation reagent in organic and organometallic synthesis to introduce the allyl group.
• Release Coatings: Employed in the manufacture of silicone release liners for labels and tapes.
• Water Repellents: A component in formulations for creating water-repellent coatings on various substrates.

Quality Control

Our Allyltrichlorosilane 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 test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Store separately from strong bases, oxidizing agents, and water.
