Description

Propylene glycol dimethyl ether ( CAS 7778-85-0 ), also known as 1,2-dimethoxypropane, is a low-viscosity ether solvent used across industrial cleaning, electronics, and coatings applications. Its fast evaporation rate and strong solvency make it a preferred carrier in formulations where residue-free performance is critical. In electronics manufacturing, it functions as a precision cleaning solvent for flux removal and surface preparation of PCBs, where clean, dry substrates are non-negotiable. Printing ink and packaging coating formulators use it as a co-solvent to control viscosity and drying speed. In solvent-based systems, automotive refinishing and underbody coating formulations incorporate it to improve flow and reduce application defects. In home care and industrial cleaning concentrates, it boosts the solvency of active ingredients against greases and hydrocarbon soils. Propylene glycol dimethyl ether is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume buyers. Technical grade is the standard commercial specification for industrial and cleaning applications. Purity levels typically range from 99% upward, with documentation including COA and purity confirmation by GC available from most suppliers. This ensures consistent performance across demanding manufacturing environments and specialized chemical processes. Contact us for supply of Propylene glycol dimethyl ether Request Quote
