Description

Allyl[(2-Cyclohexenyl-2-Ethyl)]-Dichlorosilane is a specialized organosilicon compound featuring both an allyl and a cyclohexenyl-ethyl functional group attached to a dichlorosilane core. This unique structure makes it a valuable high-purity intermediate for synthesizing advanced silicone polymers, resins, and surface-modifying agents. It is primarily sought by R&D chemists and process engineers in the specialty chemicals, advanced materials, and electronics sectors for developing products with tailored thermal, mechanical, and surface properties.

Application

• Precursor for Silicone Resins & Elastomers: Serves as a key monomer or cross-linking agent in the synthesis of novel heat-resistant and chemically stable silicone polymers.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces (e.g., silica, glass) to improve adhesion between organic polymers and fillers in composite materials.
• Intermediate for Electronic Materials: Employed in the development of silicone-based encapsulants, dielectrics, and protective coatings for semiconductor devices.
• Synthesis of Specialty Silanes: Acts as a building block for creating custom organofunctional silanes with specific reactivity for advanced R&D applications.
• Hydrophobic Coatings: A component in formulations for creating water-repellent surfaces on textiles, construction materials, and optical components.
• Adhesive & Sealant Formulations: Imparts enhanced cross-linking density and stability to high-performance adhesives and sealants.
