DOWANOL DPnB Dipropylene glycol n-butyl ether 29911-28-2 Dow Chemical Crosslinking / Coupling / Curing Agents Film forming /coalescing agents Solvent >> Glycols & glycol ether >> Propylene Glycol Coatings >> Solventborne Coatings >> Waterborne DOWANOL* DPnB glycol ether is a relatively slow-evaporating solvent which is one of our most efficient coalescents in water-borne latex systems. DOWANOL DPnB glycol ether combines a number of properties that contribute to very high latex film quality: 1) high polymer plasticizing efficiency, 2) large molecular size and therefore greater polymer mobility contribution, 3) strong partitioning to the polymer phase, and 4) relatively slow evaporation rate. This product is compatible with many different resin types. DOWANOL DPnB glycol ether also provides excellent surface tensionlowering ability, and is useful in cleaning products by itself or when blended with other products such as DOWANOL DPM glycol ether. Used alone in cold metal cleaning, DOWANOL DPnB glycol ether is a good solvent for removing oils and greases. It possesses excellent solvency, good oil solubility, effective surfactant properties, excellent coupling ability, good evaporation rate control, greater formulating flexibility, low viscosity, low odor, wide range of applications, low toxicity, practical alternative to DB (diethylene glycol butyl ether), high dilution ratio. It is used as coupling agent and solvent in household and industrial cleaners, grease and paint removers, metal cleaners, and hard surface cleaners, 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 solvent for water-reducible coatings. Dipropylene glycol n-butyl ether. Used in paint removers and latex coatings. Possesses good coupling ability. Offers very good solvency and good oil solubility.
