Diethylene Glycol Monobutyl Ether (CAS: 112-34-5), commonly referred to as Glycol Ether DB or Butyl Carbitol, is a high-boiling, slow-evaporating solvent belonging to the ethylene oxide-based glyco…
Superior Solvency: Effectively dissolves a broad spectrum of resins, including nitrocellulose, acrylics, epoxies, and alkyds.
Low Evaporation Rate: Enhances the “open time” of coatings, preventing premature drying and ensuring a smooth, high-quality finish.
High Coupling Efficiency: Acts as an intermediary to stabilize immiscible ingredients in aqueous and solvent-based systems.
High Flash Point: With a flash point exceeding 100°C, it is classified as a non-flammable liquid under many regulatory frameworks, facilitating safer storage and transport.
Water Miscibility: Completely soluble in water, making it ideal for water-borne industrial and architectural formulations.
Low Odor: Provides a more comfortable working environment compared to aggressive, high-volatility solvents.
