Application: Dipropylene glycol monomethyl ether (mixture of isomeres) for synthesis. CAS 34590-94-8, chemical formula (CH₃O)C₃H₆OC₃H₆(OH).
Mid-to slow evaporating solvent. Has 100% water solubility and is ideally suited as a coupling agent in a wide range of solvent systems. Has a higher flash point than DPM glycol ether making it easier to handle, store, and ship. Often incorporated into latex emulsion coatings; can be used to prevent shocking (coagulation of emulsion) when hydrophobic solvents are used. More broadly, its hydrophilic nature makes it an ideal coupling aid in water reducible coatings, and cleaning applications. Used with cleaners because they offer an extensive combination of basic physical and performance properties for cleaning formulations. The intermediate evaporation rate allow it to be used in a potentially wider range of systems than many other solvents.
Uses:
• Cleaners
• Resins
• Coating formulation and application
• Industrial, automotive and architectural coatings
Benefits:
• Versatile
• Wide range of applications
• Extensive combination of physical and performance properties
Properties
These values are not intended for use in preparing specifications.
DPM is completely soluble in water and is miscible with a number of organic solvents, for example ethanol, carbon tetrachloride, benzene, petroleum ether and monochlorobenzene. It is also practically non- toxic and hygroscopic, and thus lends itself well to commercial and industrial use.
Dipropylene glycol monomethyl ether is produced by the reaction of propylene oxide with methanol using a catalyst.
Dipropylene glycol monomethyl ether is stored in mild steel and /or stainless steel tanks and/or drums and can be transported by bulk vessels or tank trucks. It should be stored away from heat and sources of ignition in a cool and well-ventilated area. Dowanol DPM has a specific gravity of 0.95 and a flashpoint of 75oC (closed cup) and is not regulated for any form of transport.
Dipropylene glycol monomethyl ether is a very useful industrial and commercial chemical. One of its main commercial uses is as a solvent for paints, varnishes, inks, strippers, and degreasers. It is also utilised as a coalescing agent for water-based paints and inks where it promotes polymer fusing during the drying process. It is also a component of wood and coil coatings, as well as coatings used in the automotive industry, industrial maintainence, and metal finishing. It is also a component of hydraulic fluids and industrial degreasers and is a chemical additive in the oil production and drilling industry.
Dowanol DPM is a very useful chemical building block in the manufacture of many products. This is due to its reaction with acids, forming esters and oxidising agents which produce aldehydes, carboxylic acids and alkali metals therefore creating alcoholates and acetals.
It is this flexibility that supports the use of DPM across a range of industries and therefore makes it a component of many household items that people use every day. It is found in ceiling and wall paints and in many common cleaners including glass and surface cleaners, paint-brush cleaners, all-purpose cleaners, carpet cleaners and disinfectant cleaners. It is also found in cosmetics where it provides emollient properties and product stabilisation as well as floor and aluminium polish, leather and textile dyes, rust removers and pesticides where it acts as a stabiliser.
Dipropylene glycol methyl ether is also a chemical intermediate in the production of Dipropylene glycol monomethyl ether acetate or DPMA.

Dipropylene glycol monomethyl ether (DPM). It acts as a solvent. Reduces coating temperature, speeds up cohesion and keeps coatings in good condition. Suitable for benzene propylene emulsion, propylene alkene acid emulsion and emulsion paints. Used as anti-ice liquid in soft printing inks and silk printing inks. Applications include electrophoresis paints.
Dipropylene glycol monomethyl ether (DPM) is a clear, colorless liquid with a slight ether odor. DPM is completely soluble in water and has moderate volatility.1 Dow manufactures and sells DPM under the trade name DPM Glycol Ether.DPM is used as a solvent, coupling agent, and coalescing agent.
It is often formulated into latex coatings, water reducible coatings, and cleaners. DPM is also used as a chemical building block in the manufacture of other products. Some specific applications are household and industrial cleaners, grease and paint removers, metal cleaners, hard surface cleaners, printing ink solvents, fabric dye coupling agents, cosmetics, and herbicide stabilizers.
Propylene Glycol Monomethyl Ether (PGME) is produced by a reaction of propylene oxide with methanol using a catalyst. This reaction produces a clear, colorless liquid with an ether-like odor that spreads over distance. The properties of this compound include moderate volatility, moderate flammability and stability. Also, this chemical is soluble in water, methanol, ether and other organic solvents. The low systemic toxicity of PGME increases the attractiveness of this chemical. Uses for this chemical vary widely. PGME is primarily used as a solvent for cellulose, acrylics, dyes, inks and stains. Therefore, paints and lacquers are a prime use. PGME helps produce propylene glycol methyl ether acetate (PMA) by acting as a chemical building block. Many industrial, chemical, automotive and household cleaners include PGME as well. Other applications include use as a coalescing agent in coatings and electronics. Household applications abound including floor polish, caulking and sealants, pesticides, dyes, and inks.
PGME and PGMEA are both glycol ethers based on propylene oxide. They are solvents having a bi-functional nature (ether-alcohol and the respective acetate). They are both clear liquids, with PGMEA having a pleasant, fruity odour. The Shell Chemicals range of propylene oxide-based glycol ethers are sold under the trade name PROXITOL. How are PGME and PGMEA used? They are used as intermediates and in formulations in industrial, professional or consumer applications, mainly in surface coatings, printing inks, cleaners, agrochemical or deicing/anti-icing formulations. They are also used as extractants, and as coalescing agents and flow improvers in water-based paints.
