Dow’s PGI has many potential uses. Its most important application is as a feedstock in the production of unsaturated polyester resins. In this capacity, it is a component of high-performance reinforced plastic laminates, gel coats, and sheet molding compounds, among other goods.

Manufacturers use PG as a solvent, chemical intermediary, and heat transfer medium. It can be found in commodities such as engine coolants, polyester resins, and latex paints, as well as in airplane deicing fluid, plasticizers, lubricants, and more.

Industrial grade PG is a component of many commercial paints and varnishes, where it acts as an intermediate, and cleaners and laundry detergents, where it is a stabilizer.
