Product Overview

Dipropylene Glycol Regular Grade (DPG) is used as a reactive intermediate in the manufacturing 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
