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

Uses:

  • Cleaners
  • Textiles
  • Cosmetics
  • Resins
  • Coating formulation and application
  • Industrial, automotive and architectural coatings

Benefits:

  • Favorable enviornmental profile, superior performance for end use applications, formulations may require less Performance solvent than P or E Series

Bringing versatility to the table and other hard surfaces

DOWANOL™ DPnB glycol ether is a slow-evaporating, hydrophobic glycol ether with excellent surface tension-lowering ability and coalescing properties. DOWANOL DPnB™ glycol ether solvent has a vapor pressure that qualifies it as an exempt VOC (volatile organic compound) under the California Air Resources Board and U.S. EPA criteria for both consumer and commercial cleaning product applications. Other functional characteristics include, readily biodegradable and U.S. EPA Inerts listed for non food use.

As one of Dow’s most efficient coalescents for lowering minimum film formulation temperature in water-borne latex systems, DOWANOL™ DPnB’s properties include:

  • Active and effective ether for solvent-based coatings and water-reducible coatings
  • High polymer plasticizing efficiency
  • A larger molecular size that allows for a greater polymer mobility contribution
  • Strong partitioning to the polymer phase
  • Relatively slow evaporation rate
  • Good for the removal of soap scums and greasy soils in cleaning formulations

While versatility is key, combatibility with multiple resin types is another valued attribute that DOWANOL™ DPnB brings to the table. It can be used alone in cleaning products such as cold metal cleaning to remove oil and greases, or can be paired with other products such as DOWANOL™ DPM glycol ether.

With a variety of uses, DOWANOL™ DPnB glycol ether is a key component found in many household, industrial, metal and hard surface cleaners as well as grease and paint removers.
