Product Description
DPNB glycol ether is a slow-evaporating, hydrophobic glycol ether with excellent surface tension-lowering ability and coalescing properties. DPNB is a relatively slow-evaporating solvent which is one of our most efficient coalescents in water-borne latex systems.
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.
DPNB glycol ether also provides excellent surface tension lowering ability.
DPNB glycol ether is a good solvent for removing oils and greases
