DPNB (Dipropylene Glycol Monomethyl Ether)

Description

An efficient solvent used in, cleaning agents, and inks.

DOWANOL™ DPnB glycol ether is a slow-evaporating, hydrophobic glycol ether with excellent surface tension-lowering ability and coalescing properties.  DOWANOL™ DPnB is a relatively slow-evaporating solvent which is one ofour 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 tension lowering ability, and is useful in cleaning products by itselfor 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.
