Overview
Dipropylene glycol monopropyl ether (CAS 29911-27-1 ), also sold as Butyl Dipropasol solvent, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and electronics manufacturing.
Its controlled evaporation rate supports film formation and solvent balance in demanding formulation work. In architectural and industrial coatings, it functions as a coalescing solvent and viscosity modifier.
This chemical improves flow and leveling in waterborne systems. Electronics manufacturers use it in flux formulations and PCB cleaning processes where residue-free performance and compatibility are critical.
In printing inks and packaging applications, it helps regulate drying speed and maintain ink stability across solvent-based and UV-cure systems. It is highly effective for sensitive substrates.
Adhesive and sealant formulators incorporate it as a carrier solvent to control open time and improve substrate wetting. It is supplied as a clear liquid in standard industrial packaging including drums and IBCs.
Bulk quantities are available for high-volume users. It is typically offered at technical grade, with purity specifications aligned to industrial solvent applications for various manufacturing sectors.
Buyers should confirm exact purity levels and water content limits with suppliers when evaluating for electronics or precision cleaning end uses to ensure the material meets specific process requirements.
