DOWANOL PNB is a propylene glycol n-butyl ether. Acts as an effective coupling agent and efficient solvent for water-reducible coatings, effective coalescent for lowering the minimum film forming temperature in water-borne latex coatings, and active solvent for solvent-based coatings. Offers very good solvency and oil solubility. Provides effective surfactant properties. Possesses very good coupling ability and evaporation rate control. Exhibits greater formulating flexibility and low viscosity.
DOWANOL PNB is used in latex coatings.

DOWANOL PNB offers very high water solubility and active solvency, and is widely used in coating and cleaning applications.
DOWANOL PNB offers better viscosity reduction than heavier molecular weight glycol ethers and is particularly effective in epoxy and high solids acrylic systems.

Advantages:
• Excellent active solvency
• Very fast evaporation rate
• Low viscosity
• High dilution ratio
• Low surface tension

Used in:
• Solvent-based coatings
• Solvent-based gravure and flexographic printing inks
• Solvent blends for water-based gravure, flexographic, and silk screen printing inks
• Ball point and felt tip writing pen inks
• Household and industrial cleaners, rust removers, and hard surface cleaners

Appearance: Colorless transparent liquid

Application:
Household and industrial cleaners, oil paint removers, metal cleaners and hard surface cleaners bonding agent and a solvent; less effective water and solvent coating connection; effective water-based latex paint coagulants; solvent-based coating of the active solvent; To produce an ester, a solvent, a plasticizer chemical intermediate.

Applications
Household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners
Water and solvent-based coatings
Epoxides, acid ester derivatives, solvents and plasticizers
Water-based agricultural formulations

DOWANOL PNB is a colorless combustible liquid with an ether-like odor.
DOWANOL PNB has low water solubility and good coupling and demonstrates good solvency for coating resins. The properties of PNB support its use in agricultural, coating, cleaning, ink, textile and adhesive products.
