DPM is produced through propylene oxide addition to methanol, yielding a mixture of isomers. The product carries HS code 2909440090 for import-export classification. TICHEM supplies DPM at a minimum purity of 99.5% under industrial grade specifications, model number T100043.
DPM exhibits 100% water solubility, which supports its function as a coupling agent across aqueous and solvent phases. The flash point measures 75°C by closed cup method, higher than propylene glycol methyl ether (PM), which affects handling, storage, and shipping classifications. The intermediate evaporation rate of 0.035 (relative to n-butyl acetate = 1.0) positions DPM between fast-evaporating and slow-evaporating glycol ethers, expanding formulation flexibility. In latex emulsion coatings, DPM helps prevent shocking - coagulation of emulsion - when hydrophobic solvents are introduced.

DPM functions as a coupling agent, often in blends, for water-based dilutable coatings. In solvent-based coatings, it operates as an active solvent contributing to viscosity and flow control. The product's hydrophilic nature makes it suitable as a coupling aid in water-reducible coating systems where formulators need to maintain stability across phase boundaries.
Household and industrial cleaner formulations incorporate DPM as a coupling agent and solvent. The product appears in grease and paint removers, metal cleaners, and hard surface cleaners used in commercial and institutional maintenance operations.
DPM serves as a tail solvent for solvent-based gravure and flexographic printing inks, and as a primary solvent in solvent-based silk screen printing inks. For water-based gravure, flexographic, and silk screen printing inks, DPM acts as a coupling agent in solvent blends. In textile processing, the product functions as a coupling agent and solvent for vat dyeing operations.
In cosmetic formulations, DPM serves as a mutual solvent, coupling agent, and emollient for personal care product development. Agricultural herbicide formulations utilize DPM as a stabilizer. Floor polish and finish products incorporate DPM as a coalescent that supports film formation and durability.
TICHEM delivers DPM in three packaging formats: iron drums for standard commercial orders, intermediate bulk containers (IBC) for medium-volume facility supply, and ISO tank containers for bulk commercial procurement. All packaging meets UN transportation standards for chemical liquids.
DPM is classified under HS code 2909440090. The minimum order quantity is 1 ton, supporting initial formulation trials and small-batch production. Stock items typically dispatch within 3-7 working days. Enterprise customers may request custom labeling, batch-specific documentation, and compliance certificates tailored to destination market requirements.
TICHEM maintains quality control procedures aligned with ISO 9001 standards. Each production batch undergoes GC purity analysis, density measurement, moisture testing, and appearance inspection before release. Certificates of Analysis are available upon request for every shipment. The production facility supports annual output capacity of over 10,000 metric tons across the glycol ether portfolio, enabling consistent supply for long-term business buyers.
TICHEM supplies dipropylene glycol methyl ether at a minimum purity of 99.5%, verified through gas chromatography for each production batch.
Yes, DPM exhibits 100% water miscibility, which supports its use as a coupling agent in aqueous formulations and water-reducible coating systems.
DPM is available in 200L iron drums, 1000L IBC totes, and ISO tank containers to match order volumes from trial scale to bulk commercial procurement.
The minimum order quantity is 1 metric ton, suitable for formulation evaluation and initial production testing.
DPM has a higher flash point (75°C vs. approximately 34°C for PM) and a slower evaporation rate, which affects handling safety and formulation open time characteristics.
