Description

(5-Bicyclo[2.2.1]Hept-2-Enyl)Dimethylethoxysilane is a specialized organosilicon compound featuring a reactive norbornene moiety. This unique structure makes it a valuable silane coupling agent and monomer for advanced material synthesis. It is primarily used in the development of high-performance polymers, adhesives, and surface modification technologies. Industries requiring tailored material properties, such as specialty polymers and advanced composites, rely on this silane for its ability to bridge organic and inorganic phases.

Application

• Silane Coupling Agent: Used to modify inorganic surfaces (e.g., glass, silica, metals) to improve adhesion with organic polymers in composite materials.
• Polymer Synthesis: Serves as a functional monomer or cross-linking agent in the synthesis of specialty polymers, including polyolefins and silicones, via ring-opening metathesis polymerization (ROMP) or other addition reactions.
• Adhesive & Sealant Formulation: Enhances the bonding strength, durability, and moisture resistance of high-performance adhesives and sealants.
• Surface Modification: Imparts hydrophobic or specific functional properties to surfaces for coatings and thin-film applications.
• Rubber & Tire Industry: Used as a coupling agent in silica-filled rubber compounds to improve reinforcement, reduce rolling resistance, and enhance mechanical properties.
• Pharmaceutical & Agrochemical Intermediates: Acts as a key synthetic building block for creating complex molecules in fine chemical synthesis.

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.
