Technique for electrodeposition of water-based polymeric coating |
摘要 |
A water-based polymeric coating comprising a novolak resin is deposited electrolytically from a solution of a novolak resin upon a conductive substrate at an initial current density ranging from 10-30 milliamperes per square centimeter. The resultant coating, after cross linking by subsequent chemical treatment, is flexible, firmly adherent and evidences good thermal stability and insulation characteristics, so suggesting its use as a cover coat for printed circuits.
