- Monoethylene glycol is used in the manufacturing of alkyd resins, which are used to form films in paints, enamels, and varnishes. In the gas industry, ethylene glycol is used to remove water vapor from the gas before further processing. It is also used as a drying agent to prevent hydrate formation in gas pipelines.
