Propylene glycol monoethyl ether

Propylene glycol monoethyl ether (CAS 52125-53-8), also known commercially as PE-P and 1(or 2)-ethoxypropanol, is a glycol ether solvent used across industrial and consumer formulations.

Its slow-to-moderate evaporation rate and compatibility with both water-based and solvent-based systems make it a practical choice for formulators managing film formation and substrate wetting.

In coatings and paints, it functions as a coalescing agent and flow promoter, improving surface leveling in architectural and industrial finishes for various applications.

Cleaning product manufacturers incorporate it into hard surface cleaners and degreasers where controlled evaporation and soil solubilization are required for effective performance.

In printing inks, it supports pigment dispersion and press stability across flexographic and gravure processes, ensuring consistent quality during high-speed production runs.

Metalworking fluid formulators use it as a coupling solvent to maintain emulsion stability and improve lubricity in water-miscible cutting fluids used in heavy machinery.

Propylene glycol monoethyl ether is supplied as a clear liquid in standard drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers.

It is typically offered at technical grade, with purity specifications suited to industrial requirements. Some suppliers offer material conforming to low-impurity specifications.
