| Will CP 310W Water-Reducible Chlorinated Polyolefin Adhesion Promoter, CP 347W Water-Reducible Chlorinated Polyolefin Adhesion Promoter, or Eastman CP 349W Water-Reducible Chlorinated Polyolefin Adhesion Promoter give properties equivalent to solventborne adhesion promoters? |

| Waterborne CPOs are generally just as effective as solventborne CPOs if used in an application where cure temperatures are 250°F (121°C) or higher for 30 minutes. At lower temperatures, formulation variables of waterborne systems that contain waterborne CPOs have a major effect on adhesion performance. The type and amount of surfactant and neutralizer added or introduced with other components can affect performance. The same is true of the polymer properties such as Tg and acid number of other polymers present. Cosolvents can also have an effect on adhesion performance. |
