Description

Norbornenyl Ethyl Trimethoxysilane is a specialized organosilicon compound featuring a reactive norbornene group and hydrolyzable methoxysilane functionality. This unique structure makes it a highly effective coupling agent and reactive intermediate for advanced material synthesis. It is essential for industries requiring enhanced adhesion, cross-linking, and surface modification in polymer systems. Key users include manufacturers of high-performance silicones, advanced composites, and specialty adhesives.

Application

• As a key monomer or cross-linking agent in the synthesis of addition-cure silicone resins and rubbers.
• Surface modification of inorganic fillers (e.g., silica, glass fibers) to improve compatibility and dispersion in polymer matrices for advanced composites.
• Adhesion promoter in primers and coatings for difficult-to-bond substrates like metals, glass, and plastics.
• Reactive intermediate for creating novel hybrid organic-inorganic materials (ORMOSILs) with tailored properties.
• Component in photopolymerizable formulations for UV-curable coatings and inks, leveraging the norbornene group's reactivity.
• Modification of nanoparticles to introduce polymerizable handles for subsequent grafting or network formation.

Quality Control

Our Norbornenyl Ethyl Trimethoxysilane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) with every shipment, confirming compliance with agreed specifications. Our quality system supports traceability and meets the demands of industrial and R&D 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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain purity.
