Product Overview

Vinyltrimethoxysilane is a high-purity organosilane compound with 98% concentration, designed for precision applications in laboratory settings. This clear, colorless liquid is packaged under the AcroSeal® brand, ensuring minimal exposure to moisture and contaminants for extended shelf stability. Its molecular structure features a vinyl functional group and three methoxy groups, making it highly reactive for silane coupling reactions. The compound is particularly valued for its ability to bond organic polymers to inorganic substrates, enhancing adhesion in composite materials. With a low viscosity and high volatility, it is easily incorporated into formulations requiring uniform dispersion. The product is compatible with a wide range of solvents and can be used in both acidic and basic environments, though optimal performance is achieved under controlled pH conditions. Its purity level of 98% minimizes side reactions, making it suitable for sensitive analytical procedures. The AcroSeal® packaging provides an additional layer of protection against hydrolysis, preserving the compound’s reactivity over time.

FAQs

1. What is the shelf life of Vinyltrimethoxysilane when stored properly?

When stored in its original AcroSeal® packaging at room temperature, away from moisture and direct sunlight, the product maintains its specified purity for up to 24 months from the date of manufacture.

2. Can this product be used directly in aqueous solutions?

Vinyltrimethoxysilane hydrolyzes rapidly in water, so it should be pre-hydrolyzed in a controlled manner using an alcohol-water mixture before adding to aqueous systems to prevent premature polymerization.

3. What safety precautions should be taken when handling this chemical?

Always use in a well-ventilated area or fume hood, wear appropriate personal protective equipment including gloves and goggles, and avoid inhalation or skin contact as the compound is flammable and may cause irritation.

4. Is this product compatible with glass containers for long-term storage?

While glass is chemically resistant, the AcroSeal® packaging is specifically designed to minimize moisture ingress, so transferring to glass containers may reduce shelf life unless done under inert conditions.

5. How does the vinyl functional group affect the compound’s reactivity?

The vinyl group enables participation in free-radical polymerization reactions, allowing the silane to copolymerize with vinyl monomers or graft onto polymer backbones during processing.
