Dipropylene Glycol n-Butyl Ether (CAS 29911-28-2) is a slow-evaporating glycol ether solvent supplied in Technical Grade, a colorless to light yellow liquid that balances hydrophilic and hydrophobic character to act as a coupling agent in water-based coatings and hard surface cleaning formulations. It features a unique balance of hydrophilic and hydrophobic properties, making it an excellent coupling agent.

This Technical Grade solvent is highly effective at reducing surface tension and promoting film formation in water-based coatings. It is known for its low toxicity and high flash point compared to lighter ethers.

In cleaning formulations, it provides superior grease-cutting ability and soil removal. Its stability and solubility profile make it a preferred choice for high-performance architectural and industrial coatings.
