Dipropylene Glycol n-Butyl Ether (DPnB)

Dipropylene Glycol n-Butyl Ether (DPnB) is a high-performance glycol ether solvent widely used in coatings, cleaners, inks, and agricultural formulations. With its excellent balance of solvency, low volatility, and high boiling point, DPnB provides effective dissolution of resins, oils, and polymers while enhancing flow and leveling in water-based and solvent-based systems. Its coupling ability makes it particularly valuable in formulations where stability, reduced surface tension, and improved performance are critical.

In industrial and institutional cleaners, DPnB improves degreasing power and cleaning efficiency. In coatings and paints, it functions as a coalescent and coupling agent that promotes film formation and durability. Its low odor and favorable safety profile compared to higher-volatility solvents also make it suitable for use in sensitive environments, including printing inks and certain agricultural products. The versatility of DPnB ensures consistent results across a broad spectrum of industries.
