  • Curable, weldable coating compositions
    Patent number: 6984674
    Abstract: A curable coating composition is disclosed comprising a resinous binder comprising (a) a reaction product of an epoxy-containing polymer with a compound containing phosphorus acid groups, the reaction product having reactive functional groups, and (b) a curing agent having functional groups reactive with the functional groups of (a). An electroconductive pigment is dispersed in (a) such that the weight ratio of the electroconductive pigment to (a) plus (b) is within the range of 0.5 to 9.0:1. When the curable coating composition is deposited and cured on a metal substrate, the cured coating is weldable.
    Type: Grant

  • Article having a chip-resistant electrodeposited coating and a process for forming an electrodeposited coating
    Patent number: 6423425
    Abstract: An electrodeposition process is provided for applying an elastomeric thermosetting, film-forming polymer to a corrosion-resistant electrically conductive substrate that is free of an electrodeposited coating. The elastomeric polymer typically is a polyurethane, a polyurea or a poly(urethane urea). The film-forming coating applied by this process provides chip resistance to the substrate. A coated article that is prepared according to the process is also provided.
