Description

Allylhexyldichlorosilane is a specialized organosilicon compound featuring both allyl and hexyl functional groups attached to a reactive dichlorosilane core. This unique structure makes it a valuable intermediate for introducing hydrophobic, cross-linkable, and organofunctional properties into advanced materials. It is primarily utilized by R&D chemists and process engineers in the silicone polymer, surface modification, and specialty chemical synthesis sectors. The compound's dual reactivity allows for tailored material design in demanding industrial applications.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce long-chain alkyl and reactive allyl groups into silicone elastomers and resins, enhancing hydrophobicity and mechanical properties.
• Surface Treatment Agent: Used to create hydrophobic, oleophobic, or adhesion-promoting monolayers on glass, metal, and mineral surfaces for protective coatings.
• Intermediate for Silane Coupling Agents: Serves as a key precursor in the synthesis of novel bifunctional silane coupling agents for composite materials and filled polymer systems.
• Adhesive & Sealant Formulations: Incorporated to improve the moisture-curing characteristics, flexibility, and bonding performance of silicone-based adhesives and sealants.
• Specialty Chemical Synthesis: Employed in organic and organometallic synthesis to build complex molecular architectures for pharmaceuticals, agrochemicals, and liquid crystals.
• Release Coatings: A component in formulations for non-stick and release coatings on papers, films, and industrial molds.

Quality Control

Our Allylhexyldichlorosilane is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC), NMR, and Karl Fischer titration. We adhere to stringent internal quality standards, and a Certificate of Analysis (COA) detailing purity, identity, and key physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is hygroscopic (moisture-sensitive) and reacts with strong bases; it must be kept under an inert atmosphere (e.g., nitrogen or argon) and isolated from incompatible materials such as strong oxidizers and bases.
