Dipropylene glycol methyl ether acetate

Dipropylene glycol methyl ether acetate (CAS 88917-22-0), commonly abbreviated as DPMA and sold under the trade name Dowanol DPMA, is a slow-evaporating glycol ether ester solvent used across coatings, electronics, and printing industries. Its controlled evaporation rate makes it a preferred choice where extended open time and film leveling are critical to end-product quality. In industrial and architectural coatings, DPMA supports smooth film formation in high-solids and waterborne systems.

By slowing solvent release and improving flow, it ensures a high-quality finish. Electronics manufacturers use it in photoresist stripping and cleaning formulations, where its solvency for resinous residues reduces rework rates significantly. Flexographic and gravure ink formulators incorporate DPMA to manage viscosity and drying profiles on high-speed printing lines. In adhesives and sealants, it functions as a coalescing solvent that aids substrate wetting and improves adhesion.

This versatile solvent is particularly effective when bonding to difficult surfaces. DPMA is supplied as a clear liquid in standard packaging including drums and IBC totes, with bulk availability for high-volume industrial users. Technical grade is the primary commercial specification, meeting requirements for coatings and electronics processing applications. Purity levels and moisture content specifications vary by supplier, so buyers should confirm conformance.

It is essential to verify all internal formulation standards before procurement. This ensures the material meets the specific needs of your industrial process and maintains the integrity of the final chemical application.
