METHOXYTRIMETHYLSILANE Chemical Properties,Uses,Production

Chemical Properties

METHOXYTRIMETHYLSILANE is clear colorless liquid

Uses

Methoxytrimethylsilane plays an important role in the synthesis of organic compounds and used as water disgusting. It is used in the preparation of alfa-lithioalkoxysilanes by treating with tert-butyllithium.

Uses

Superhydrophobic recycled polyethylene terephthalate (rPET) aerogels can be fabricated by using rPET fibers and polyvinyl alcohol (PVA) and can be coated on MTMS. MTMS on diglycidyl bisphenol A resin (epoxy resin) also shows weathering resistance on exposure to UV by lowering the effect of color change by 45%.

Uses

Effect of chemical modification of diglycidyl bisphenol A based epoxy resin with methyltrimethoxy silane (MTMS) was studied. It was used to quench lab ware with MTMS while handling HF/pyridine.

General Description

Methoxytrimethylsilane (MTMS) is a silylating agent, which is majorly used to provide a hydrophobic surface coating with a high water contact angle and low surface energy.

Chemical Reactivity

Methoxytrimethylsilane can react with strong oxidizing agents, strong acids, it decomposes and releases carbon monoxide (CO), carbon dioxide (CO2) and silicon dioxide.
