Product Technical Details

Product Overview

Ethenyldiethoxymethylsilane is a highly reactive organosilicon compound widely recognized for its exceptional performance in polymer modification and crosslinking applications. As a key functional silane, it features a vinyl group that enables efficient participation in addition reactions, alongside hydrolyzable ethoxy groups that facilitate bonding with inorganic substrates. This dual functionality makes it an indispensable raw material for manufacturing high-performance silicone rubbers and elastomers.

Our manufacturing process ensures consistent molecular integrity and minimal impurity levels, catering to the rigorous demands of advanced material science. The compound is supplied as a colorless transparent liquid, ready for integration into complex formulation systems where stability and reactivity are paramount.

Industrial Applications

The primary application of Ethenyldiethoxymethylsilane lies in the production of silicone rubber, where it acts as a critical crosslinking agent or co-monomer. By incorporating this silane into polymer chains, manufacturers can significantly enhance the mechanical strength, thermal stability, and aging resistance of the final rubber product. It is particularly effective in high-consistency rubber (HCR) and liquid silicone rubber (LSR) formulations.

Beyond rubber synthesis, this chemical serves as a versatile intermediate for creating specialized surface treatments and adhesion promoters. The vinyl functionality allows for grafting onto various organic backbones, while the ethoxy groups ensure robust adhesion to glass, metals, and minerals. This makes it valuable in composite materials, coatings, and sealants requiring durable interfacial bonding.

Quality Assurance And Storage

We adhere to strict quality control protocols to guarantee every batch meets international standards. Each shipment is accompanied by a Certificate of Analysis (COA) verifying purity, density, and refractive index parameters. Our facility employs advanced gas chromatography methods to monitor impurity profiles, ensuring optimal performance in downstream synthesis.

For storage, maintain the product in a cool, ventilated area away from direct sunlight and moisture sources. The chemical is flammable with a low flash point, so appropriate safety measures regarding fire prevention and static discharge must be observed. Standard packaging includes 170 kg drums, with customization available to suit specific logistical requirements for global export.
