Popis

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.

Application

Effect of chemical modification of diglycidyl bisphenol A based epoxy resin with methyltrimethoxy silane (MTMS) was studied. 1 It was used to quench lab ware with MTMS while handling HF/pyridine.{90}

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%.
