ARCOSOLV® DPM - (Dipropylene Glycol (Mono) Methyl Ether) - is a colorless, combustible liquid with low toxicity having a mild, pleasant odor. It is completely water soluble, miscible with a number of organic solvents and has good solvency for a number of substances.
Benefits and Applications
Coatings: ARCOSOLV DPM provides good solvency for a wide variety of resins including acrylic, epoxies, alkyds, polyesters, nitrocellulose and polyurethanes. ARCOSOLV DPM has a relatively low vapor pressure (volatility) and evaporates at a slow rate. Key properties for coating applications include complete water miscibility and good coupling ability.
Cleaners: Surface tension reduction and slow evaporation are some of the benefits of using ARCOSOLV DPM in cleaning formulations. DPM has a low odor and slow evaporation rate. It is a good choice for wax strippers and floor cleaners, which are spread over a large area. When used in an enclosed area, a floor cleaner containing a fast-evaporating solvent might produce an undesirable amount of solvent vapor. ARCOSOLV DPM provides good solvency for polar and non-polar materials.
Other Applications: The properties listed in the previous section also support the use of ARCOSOLV DPM in agricultural, cosmetic, electronic, ink, textile and adhesive products.
Toxicology/Regulatory
ARCOSOLV DPM has a low degree of acute toxicity and is a slight eye irritant. OSHA has established a 100 ppm TWA for inhalation with a notation that ARCOSOLV DPM may be absorbed through the skin. No skin absorption hazard has been found.
Regulatory Status: Refer to Material Safety Data Sheet for more specific information.
ARCOSOLV DPM and all propylene glycol ethers are not included under the category glycol ethers as defined in the Clean Air Act Amendments of 1990.
ARCOSOLV DPM is not subject to the reporting requirement of CERCLA or the reporting requirements established by SARA Title 111, section 313 and 40CFR372.
ARCOSOLV DPM is on the U.S. TSCA inventory and the EEC's EINECS, Canadian DSL, Australian, and Japanese chemical inventories.
Storage and Handling
General industry practice is to store ARCOSOLV DPM in carbon steel vessels. Avoid contact with air when storing for long periods of time.
Store only in tightly closed, properly vented containers away from heat, sparks, open flame or strong oxidizing agents. Use only non-sparking tools. Ground containers before beginning transfer. Electrical equipment should conform to national electric code.
Handle empty containers carefully. Combustible e residue remains after emptying. Store in properly lined steel or stainless steel to avoid slight discoloration from mild steel. Glycol ethers should never be stored or handled in copper or copper alloys. This product may absorb water if exposed to air. However, it is not subject to the reporting level established by SARA Title 111, section 313 and 40CFR372.
ARCOSOLV DPM is classified as a combustible liquid under SARA, Title 111, sections 311/312, but is not subject to the reporting requirements of SARA Title III, section 313.
Undue exposure or spillage should be strictly avoided as a matter of good practice. Refer to the Material Safety Data Sheet for ARCOSOLV DPM for more specific information.
