What is Dipropylene glycol monopropyl ether?

Dipropylene glycol monopropyl ether (CAS 29911-27-1), also sold as Butyl Dipropasol solvent, is a slow-evaporating glycol ether solvent.

Coatings: coalescing solvent and viscosity modifier in architectural and industrial coatings
Waterborne systems: improves flow and leveling
Electronics: flux formulations and PCB cleaning
Printing inks and packaging: regulates drying speed and maintains ink stability in solvent-based and UV-cure systems
Adhesives and sealants: carrier solvent controlling open time and substrate wetting
Its controlled evaporation rate supports film formation and solvent balance.

Good to know: Buyers should confirm exact purity levels and water content limits with suppliers for electronics or precision cleaning end uses.
