`
`Product Description
`
`DOWANOLTM DPnB glycol ether is a slow-evaporating, hydrophobic glycol ether with
`
`excellent surface tension-lowering ability and coalescing properties. DOWANOLTM
`
`DPnB is a relatively slowevaporating solvent which is one of our most efficient
`
`coalescents in water-bome latex systems. DOWANOLTM 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.
`
`DOWANOLTIVI DPnB glycol ether also provides excellent surface tension lowering
`ability, and is useful in cleaning products by itself or when blended with other products
`such as DOWANOLTM DPM glycol ether. Used alone in cold metal cleaning,
`DOWANOLTM DPnB glycol ether is a good solvent for removing oils and greases.
`
`0 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.
