Polyimide modified epoxy resins in aqueous emulsions for lamination and electrodeposition |
摘要 |
Disclosed in an emulsion having a discontinuous phase that consists of a water dispersed or water emulsified epoxy resin in water having at least two epoxide groups, a water soluble salt of an imide compound having at least one carboxyl group, and a crosslinking agent; the discontinuous phase has excess epoxide functionality. The continuous phase is water. A method of forming a coating on a conductive substrate is also disclosed. The substrate and an electrode are immersed into the emulsion and a direct current is applied between the substrate and the electrode to electrophoretically deposit a coating on the substrate of the epoxy resin, the imide compound, and the crosslinking agent. The substrate is removed from the emulsion and is heated to a temperature sufficient to cure the coating.
