What is Dipropylene glycol monobutyl ether?
Dipropylene glycol monobutyl ether (CAS 29911-28-2), commonly abbreviated as DPNB, is a slow-evaporating glycol ether solvent used in coatings, cleaning, and personal care formulations.
Where is Dipropylene glycol monobutyl ether used?
- Coatings: coalescing agent and flow promoter that improves film leveling and reduces surface defects in waterborne systems
- Adhesives and sealants: adjusts open time and enhances substrate wetting
- Printing inks: controls viscosity and drying profiles in packaging inks
- Personal care: solvent and coupling agent in hair care treatments and skin cleansers
- Its controlled evaporation rate and compatibility with water-based and solvent-based systems support film formation and flow behavior.
Commercial specifications
- Purity typically 98% or higher
- Drum and IBC quantities; bulk tanker options
