DOWANOL™ DPnB Glycol Ether

A slow-evaporating, hydrophobic glycol ether with excellent surface tension-lowering ability and coalescing properties. It has a near mid-range balance of hydrophobic and hydrophilic characteristics, and it offers significant water solubility. It is one of our most efficient coalescents in water-borne latex systems. It 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. It also provides excellent surface tension lowering ability, and is useful in cleaning products by itself or when blended with other products. Used alone in cold metal cleaning, it is a good solvent for removing oils and greases. An excellent choice for coatings applications, this product provides outstanding coalescing and film properties. INCI Name: Dipropylene glycol n-butyl ether
