1. Polyester
Mono Ethylene Glycol is an essential raw material for Polyester. Ethylene Glycol reacts with PTA / DMT to produce polyester.
2. Adhesives, Sealants, and Coatings
Mono Ethylene Glycol and D-Ethylene Glycol have used in latex based paint formulation. These glycols are also used to produce
acrylate and methacrylate resins for coatings, adhesives, and paints.
3. Alkyd Resins for Paints and Coatings
Mono Ethylene Glycol is used as a reactant in the manufacture of Alkyd resins which are used in paints, enamels, and varnishes.
4. Antifreeze
Ethylene Glycol (MEG) is used as an active ingredient in engine coolants and antifreeze, offering benefits including a high
boiling point, low vapor pressure, excellent heat transfer abilities, and the ability to depress the freezing point of water.
5. Others
A) Dyes & Inks
MEG finds applications in products like Dyes & Inks for High-speed printing.
B) Humectants
Glycols being hygroscopic in nature are also used as Humectants for paper etc.
