DOWANOL PnB glycol ether is extensively used in heavy-duty cleaning formulations. It does an excellent job of solvating and coupling hydrophobic greases and oils in household as well as industrial formulations. It is partly water soluble and miscible with most organic solvents.
* Suggested applications:
- Coupling agent and solvent in household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners.
- Effective coupling agent and efficient solvent for water-reducible coatings.
- Effective coalescent for lowering minimum film formation temperature (MFFT) in water-borne latex coatings.
- Active solvent for solvent-based coatings.
- Chemical intermediate for the production of epoxides, acid ester derivatives, solvents, and plasticizers.
- Effective coupling agent in water-based agricultural formulations.
* Features:
- Excellent solvency
- Good oil solubility
- Effective surfactant properties
- Excellent coupling ability
- Good evaporation rate control
- Greater formulating flexibility
- Low viscosity
- Wide range of applications
- Low toxicity
- Practical alternative to EB (ethylene glycol butyl ether)
- High dilution ratio
- Colorless |
