The major end use for MPG is as a raw material in the manufacturing of unsaturated polyester resins. MPG is used as an active ingredient in antifreeze and as an anti-icing agent for car windshields, boats and airplane wings. MPG has a very low freezing point, and acts as a thickening agent, which helps the fluid adhere to surfaces. MPG is used as a solvent in paints, coatings, enamels and varnishes. MPG improves the properties of paints because its slow evaporation time lengthens the time the paint remains suitable for application.
MPG is manufactured in two different grades in Iran, industrial grade and pharma grade.
