Dipropylene glycol monomethyl ether

Applications of Dipropylene Glycol Monomethyl Ether (DPM, CAS: 34590-94-8)

Dipropylene glycol monomethyl ether (DPM) is a high-boiling, slow-evaporating solvent with excellent solvency for both polar and non-polar substances. It is widely used in industrial and consumer applications due to its low toxicity, mild odor, and good water compatibility.

Primary Application Areas

1. Paints, Coatings, and Inks

• Solvent in water-based & solvent-based coatings – improves flow, leveling, and film formation.

• Coalescing agent in latex paints – helps bind polymer particles during drying.

• Inkjet ink formulations – enhances dye/pigment solubility and print quality.

2. Cleaning & Degreasing

• Industrial & household cleaners – effective for removing oils, greases, and resins.

• Electronics cleaning – used in precision cleaning of circuit boards and optical components.

• Metal degreasing – safe for aluminum, steel, and other metals.

3. Chemical Processing & Manufacturing

• Intermediate in chemical synthesis – used to produce esters and other derivatives.

• Coupling agent – improves miscibility of water and organic solvents.

• Reaction medium in pharmaceuticals and agrochemicals.

4. Personal Care & Cosmetics

• Solvent in perfumes, lotions, and hair care products – improves fragrance retention.

• Carrier in antiperspirants & deodorants – enhances active ingredient delivery.

• Low-irritation alternative to harsher glycol ethers.

5. Automotive & Industrial Fluids

• Brake fluids & hydraulic fluids – provides lubricity and moisture resistance.

• Fuel additives – helps prevent icing and improve cold-weather performance.

6. Adhesives & Sealants

• Plasticizer & viscosity reducer in epoxy, acrylic, and PU adhesives.

• Improves wetting & adhesion in sealants for construction and automotive use.

7. Textile & Leather Processing

• Dye carrier – improves dye penetration in synthetic fibers.

• Leather finishing agent – enhances softness and water resistance.
