Description

Allyl(Chloropropyl)Dichlorosilane is a highly reactive organosilicon compound characterized by its bifunctional allyl and chloropropyl groups. This unique structure makes it a valuable intermediate for introducing silane functionality into polymer backbones and organic molecules, enabling cross-linking, adhesion promotion, and surface modification. It is essential for R&D chemists and production engineers in the silicone polymer, specialty adhesives, and advanced materials sectors seeking to develop products with tailored mechanical and surface properties.

Application

• Silicone Polymer Modification: Serves as a key monomer or cross-linking agent in the synthesis of specialty silicone elastomers and resins, enhancing thermal stability and mechanical strength.
• Adhesion Promoter: Used in primer formulations to improve the bond between organic polymers (like epoxies or polyurethanes) and inorganic substrates such as glass, metals, or minerals.
• Surface Functionalization: Employed to modify the surface of silica, nanoparticles, and other fillers to improve compatibility and dispersion within polymer matrices.
• Intermediate for Further Synthesis: The reactive chlorosilane and allyl groups provide handles for subsequent hydrosilylation or nucleophilic substitution reactions, enabling the creation of custom silane coupling agents.
• Water Repellent Treatments: A precursor in formulations for creating water-resistant coatings on construction materials, textiles, and paper.
• Research & Development: A versatile building block in academic and industrial R&D for exploring new organosilicon chemistry and hybrid material systems.

Quality Control

Our Allyl(Chloropropyl)Dichlorosilane is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay by GC and impurity profiling, to meet exacting customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and 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 at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts vigorously with strong acids and bases; it must be kept under an inert atmosphere (e.g., nitrogen or argon) and away from incompatible materials.
