Description

Diphenylvinylchlorosilane is a highly reactive organosilicon monomer featuring both phenyl and vinyl functional groups. This compound is a critical building block in the synthesis of advanced silicone polymers and specialty silanes, valued for its ability to introduce cross-linking sites and modify surface properties. It is essential for manufacturers in the silicone, electronics, and advanced materials industries seeking to develop high-performance, thermally stable, and hydrophobic materials.

Application

• Silicone Polymer Synthesis: A key monomer for producing phenyl- and vinyl-modified polysiloxanes, enhancing thermal stability, refractive index, and mechanical properties.
• Surface Modification Agent: Used as a coupling agent or surface treatment to impart hydrophobicity and improve adhesion between organic polymers and inorganic substrates like glass or metals.
• Cross-linking Agent: Serves as a reactive site in the production of heat-curable silicone rubbers and resins, facilitating the formation of durable, three-dimensional networks.
• Electronic Encapsulants & Potting: A precursor for silicones used in protecting sensitive electronic components due to its contribution to thermal and environmental resistance.
• Specialty Coatings: Incorporated into formulations for high-temperature, release, or protective coatings where chemical inertness and durability are required.
• Intermediate for Further Functionalization: The reactive chlorosilane and vinyl groups allow for subsequent chemical modifications to create custom silanes with tailored properties.

Quality Control

Our Diphenylvinylchlorosilane is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling. A Certificate of Analysis (COA) detailing all specifications 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 at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts vigorously with strong acids, bases, and water. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and to minimize volatilization.
