Product Overview
Methyltrimethoxysilane, 97% purity, is a high-performance silane coupling agent designed for precision lab applications. This organosilicon compound features a methoxy functional group, enabling strong covalent bonding with inorganic substrates like glass, metals, and ceramics. Its low viscosity and high reactivity make it ideal for surface modification, enhancing adhesion in composites, coatings, and sealants. The AcroSeal® packaging ensures minimal moisture exposure, preserving reactivity and extending shelf life. With a boiling point of ~102°C and flash point of 15°C, it requires careful handling under inert conditions. This grade is free from stabilizers, ensuring consistent performance in sensitive applications like chromatography or nanotechnology. Its compatibility with organic solvents allows seamless integration into formulations, while the methyl group provides hydrophobic properties for tailored surface energy adjustments.
FAQs
1. What is the shelf life of Methyltrimethoxysilane 97% in unopened AcroSeal® packaging?
When stored under nitrogen at 2-8°C in unopened AcroSeal® bottles, the product retains 97% purity for 24 months from the date of manufacture. Always verify the batch-specific expiry date on the label.
2. Can this silane be used directly for glass surface activation without dilution?
Direct application is possible but not recommended due to rapid hydrolysis. For glass activation, dilute to 1-2% in ethanol or acetone, adjust pH to 4-5 with acetic acid, and apply under controlled humidity.
3. What precautions are needed when handling the 100ML pack compared to the 1LT bottle?
The 100ML pack has higher vapor concentration risk due to smaller headspace. Use in a fume hood with nitrogen purging, and limit opening duration. The 1LT bottle allows slower dispensing but requires grounding to prevent static discharge.
4. How does the AcroSeal® packaging differ from standard amber glass bottles for this chemical?
AcroSeal® uses a PTFE-lined cap with a nitrogen headspace and moisture-absorbing desiccant, reducing hydrolysis to <0.5% over 12 months. Standard amber glass lacks these features, leading to faster degradation.
5. What’s the recommended drying method after silane treatment to avoid residue formation?
Use a two-step process: first, air-dry at room temperature for 10 minutes to allow hydrolysis, then cure at 110°C for 30 minutes in a vacuum oven to remove methanol byproducts and complete condensation.
