Description

5-(Trimethoxysilyl)Bicyclo[2.2.1]Hept-2-Ene CAS NO 7538-46-7 is a highly functionalized norbornene derivative featuring a reactive alkene group and a hydrolyzable trimethoxysilyl moiety. This unique bifunctional structure makes it a valuable silane coupling agent and crosslinking monomer for advanced material synthesis. It is essential for industries requiring enhanced adhesion between organic polymers and inorganic substrates, as well as for creating high-performance, cross-linked networks. Key users include manufacturers in the specialty polymers, advanced composites, adhesives, and coatings sectors.

Application

• Silane Coupling Agent: Used to improve the adhesion and compatibility between organic resins (e.g., epoxies, polyurethanes) and inorganic materials like glass, metals, and minerals in composite materials.
• Crosslinking Monomer: Incorporated into polymer backbones (via ring-opening metathesis polymerization - ROMP) or as a crosslinker to create thermally stable, high-strength networks with tailored properties.
• Surface Modification: Applied to treat fillers (e.g., silica, glass fibers) to enhance their dispersion in polymer matrices and improve mechanical properties of the final composite.
• Adhesive & Sealant Formulations: Serves as an adhesion promoter in high-performance structural adhesives, sealants, and potting compounds, especially for challenging substrates.
• Specialty Coatings: Used in the formulation of scratch-resistant, corrosion-resistant, and durable coatings where strong substrate bonding is critical.
• Hybrid Material Synthesis: A key precursor in sol-gel chemistry for creating organic-inorganic hybrid materials with precise nanostructures.
• Pharmaceutical & Agrochemical Intermediates: The strained norbornene structure can be utilized in synthesis for creating complex molecules in life science applications.

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