Dipropylene Glycol Regular Grade (DPG)
Dipropylene Glycol Regular Grade (DPG) is used as a reactive intermediate in the manufacture of high-performance unsaturated polyester resins, polyurethanes and plasticizers. DPG from Dow has great solvency, a low evaporation rate, low toxicity, high viscosity and low odor, making it a chemical intermediate of choice for many applications, including:
- High-volume plasticizer
- Reactant in unsaturated polyurethane resins, adding flexibility and hydrolytic stability
- Initiator in urethane polyols, and as the polyol itself in some rigid polyurethane systems
- Reactive diluents in radiation-cured resins and coatings, cutting viscosity and enabling easier application
Other effective uses of DPG are:
- Hydraulic brake fluid formulations
- Cutting oils
- Textile lubricants
- Printing inks
- Coatings
- Industrial soaps
- Solvents for agricultural chemicals such as insecticides
DPG is available from Dow in drum and bulk quantities.
