Description

Vinyldiphenylmethylsilane is a versatile organosilicon compound featuring a reactive vinyl group and two phenyl substituents. This unique structure makes it a valuable intermediate for synthesizing advanced silicone polymers and functional materials. It is particularly sought after by manufacturers in the specialty chemical and advanced materials sectors for applications requiring tailored surface properties and cross-linking capabilities.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linking agent in the synthesis of phenyl-containing silicone resins, rubbers, and elastomers, enhancing thermal stability and refractive index.
• Surface Treatment & Coupling Agent: Used to modify inorganic surfaces (e.g., silica, glass) to improve adhesion, hydrophobicity, and compatibility with organic matrices in composite materials.
• Pharmaceutical & Agro-Intermediate: Serves as a building block in the synthesis of more complex organosilicon molecules for pharmaceutical and agrochemical applications.
• Hydrosilylation Reactions: The vinyl group readily participates in hydrosilylation, a fundamental reaction for creating custom siloxane structures and functional silicones.
• Advanced Material Research: Employed in R&D for developing novel materials such as liquid crystals, OLED components, and silicon-based dendrimers.
• Adhesive & Sealant Formulations: Incorporated into formulations to enhance the performance, durability, and environmental resistance of high-end adhesives and sealants.

Quality Control

Our Vinyldiphenylmethylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, acids, and bases. The container should be kept tightly sealed under an inert atmosphere to prevent moisture absorption and potential oxidation.
