Description

(3-Chloropropyl)Trivinylsilane CAS NO 954114-17-1 is a specialized organosilicon compound featuring a reactive chloropropyl group and three vinyl functionalities. This unique bifunctional structure makes it a valuable cross-linking agent and versatile chemical building block for advanced material synthesis. It is primarily needed by manufacturers in the silicone polymers, adhesives, and specialty coatings industries seeking to introduce specific reactive sites and enhance material properties.

Application

• Silicone Polymer Modification: Acts as a key monomer or cross-linker in the synthesis of custom silicone resins and elastomers, introducing reactive vinyl and chloropropyl sites for further functionalization.
• Adhesive & Sealant Formulations: Used to enhance the adhesion, cross-linking density, and thermal stability of high-performance silicone-based adhesives and sealants.
• Surface Coupling Agent: Serves as a silane coupling agent to improve the bond between inorganic materials (like glass or minerals) and organic polymer matrices in composite materials.
• Specialty Coatings: Incorporated into coating formulations to provide improved surface hardness, chemical resistance, and weatherability.
• Pharmaceutical & Agro-Intermediate Synthesis: Utilized as a versatile synthetic intermediate for constructing more complex molecules in pharmaceutical and agrochemical research.
• LED Encapsulation Materials: Employed in the production of high-refractive-index, durable silicone encapsulants for LED packaging.

Quality Control

Our (3-Chloropropyl)Trivinylsilane is produced under stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality assurance processes.

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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
