Is DPnP the same as Dipropylene Glycol n-Butyl Ether?

No. DPnP is Dipropylene Glycol n-Propyl Ether CAS 29911-27-1, while DPnB is Dipropylene Glycol n-Butyl Ether CAS 29911-28-2. The two glycol ethers have different alkyl groups, evaporation rates and solvent balances, so they should not be treated as interchangeable.

Which specifications and physical properties matter for DPnP?

Compare assay or composition, water, color, acidity or pH, density, distillation range and isomer or homolog distribution. Typical DPnP is a clear colorless liquid with density about 0.916-0.921 g/mL, boiling point about 212 °C and flash point around 88-94 °C.

What is Dipropylene Glycol n-Propyl Ether used for?

DPnP is used as a slow-evaporating coalescing solvent and viscosity modifier in architectural and industrial coatings, printing inks, cleaners, adhesives and textile formulations. It is also used in electronics applications such as flux formulations and PCB cleaning where residue-free performance and substrate compatibility are important.

Can DPnP be considered a low-VOC solvent in every market?

Do not assume VOC status. Whether DPnP is classified or treated as a VOC depends on the local regulation, testing method and specific formulation use. Confirm the destination market, required documentation and formulation limits before relying on a VOC claim.

How should DPnP be stored and handled?

Store in tightly closed, compatible containers in a cool, dry, ventilated area away from heat, ignition sources and strong oxidizers. Avoid moisture ingress and contamination, and state the required assay, water content, intended use, quantity, packaging and destination in the RFQ.
