DOWANOL™ DPM Glycol Ether

DOWANOL™ DPM glycol ether is a mid to slow evaporating solvent that has 100% water solubility and is ideally suited as a coupling agent in a wide range of solvent systems. This product has a higher flash point than DOWANOL™ PM, making it easier to handle, store, and ship.

Used in:

  • Water and solvent-based coatings
  • Household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners
  • Vat dyeing fabrics
  • Cosmetic formulations
  • Agricultural herbicides

Advantages:

  • Powerful solvency
  • Moderate evaporation rate
  • 100% water solubility
  • High dilution ratio
  • Excellent coupling ability
