  • Process for forming a two-coat electrodeposited composite coating the composite coating and chip resistant electrodeposited coating composition
    Patent number: 6248225
    Abstract: A process for applying two electrodeposited coatings, one on top of the other, to an electrically conductive substrate is provided. An electrically conductive first coating is applied to provide for corrosion resistance and a second polyurethane-based coating is applied to the first coating to provide chip resistance. Also, aqueous dispersions of the polyurethane coating compositions are disclosed.

  • Crosslinked unsaturated polyesters as flatting agents in aqueous electrocoating compositions
    Patent number: 5464887
    Abstract: An aqueous electrocoating composition useful in a method of electrodeposition contains an electrodepositable resin, optionally a curing agent and a microparticulate crosslinked unsaturated polyester flatting agent. The microparticulate flatting agent provides the desired flatting effect without compromising coating properties such as corrosion resistance and flexibility.
