DOWANOL™ PnB Glycol Ether

A fast-evaporating, hydrophobic glycol ether with high solvency and excellent coupling abilities. It is partly water soluble and miscible with most organic solvents. This is extensively used in heavy-duty cleaning formulations.

Uses:

  • Textiles
  • Cosmetics
  • Resins
  • Coating formulation and application
  • Industrial, automotive and architectural coatings
  • Glass and all-purpose cleaners where heightened results can be seen in combination with selected other glycol ether solvents
  • Various household and industrial cleaners as a coupling agent and solvent
  • Grease and paint removers as a coupling agent and solvent
  • Metal and hard surface cleaners as a coupling agent and solvent
  • Water-reducible aerosol paint formulations as a coupling cosolvent
  • Effective coalescents in water-borne latex coatings while belended with other P-series glycol ethers
  • Good for removing soap scum and greasy soils in cleaning applications

Benefits:

  • Favorable enviornmental profile, superior performance for end use applications, formulations may require less Performance solvent than P or E Series
