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

用途:

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

优势:

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