Description

Vinylphenyldimethylsilane is a versatile organosilicon monomer featuring a reactive vinyl group and a phenyl substituent. This compound is valued for its dual functionality, enabling its use as a key building block in the synthesis of advanced silicone polymers and hybrid organic-inorganic materials. It is primarily sought by manufacturers in the silicone resin, specialty adhesive, and advanced coating industries for developing products with enhanced thermal stability, chemical resistance, and tailored surface properties.

Application

• Silicone Polymer Modification: Serves as a reactive monomer for introducing phenyl and vinyl groups into polysiloxane backbones, improving thermal and oxidative stability.
• Hybrid Material Synthesis: A crucial precursor in sol-gel processes for creating silicone-based hybrid coatings and composites with organic polymers.
• Adhesive & Sealant Formulations: Used in cross-linking systems for high-performance silicone adhesives and sealants, enhancing adhesion and durability.
• Surface Treatment & Coupling Agent: Functions as a silane coupling agent to modify surface properties of inorganic fillers like silica or glass, promoting compatibility with organic matrices.
• Release Coatings: Employed in the production of silicone-based release liners for labels and tapes.
• Pharmaceutical & Electronic Intermediates: Acts as an intermediate in the synthesis of more complex organosilicon compounds for specialized applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is easily oxidized and should be handled and stored under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent degradation. Keep away from heat, sparks, and open flame.
