Description

N,n-Dimethylaminovinyldiethoxysilane is a specialized organosilicon compound featuring both amino and vinyl functional groups. This unique bifunctional structure makes it a highly effective coupling agent and surface modifier, crucial for enhancing the adhesion and compatibility between inorganic materials and organic polymers. It is essential for manufacturers in the silicone, adhesive, and advanced composite materials industries seeking to improve product performance and durability. Its reactivity allows for tailored surface properties in demanding technical applications.

Application

• As a coupling agent in mineral-filled composites (e.g., fiberglass, silica-filled rubbers) to improve mechanical strength and moisture resistance.
• As a surface treatment agent for glass fibers, fillers, and pigments to enhance dispersion and bonding within polymer matrices.
• In the formulation of adhesives and sealants to promote adhesion to difficult substrates like metals and glass.
• As a key intermediate in the synthesis of specialty silicone polymers and functional silanes.
• For the modification of resins (epoxy, phenolic) to introduce amino functionality and improve cross-linking.
• In waterproofing treatments for construction materials, leveraging its moisture-reactive ethoxy groups.

Quality Control

Our production of N,n-Dimethylaminovinyldiethoxysilane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and titration to verify critical parameters such as assay, identity, and moisture content. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, ensuring full traceability and compliance with your material specifications.

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 a dry inert atmosphere (e.g., nitrogen) after opening to prevent degradation.
