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
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%.
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}
