  • Patent number: 7264705
    Abstract: An improved aqueous cathodic electrocoating composition that contains an anti-crater agent which is a water-reducible polyester resin having an acid value less than 40 mg KOH/g. The water-reducible polyester is the reaction product of (1) a hydroxy cyclic carbonate; (2) a polycarboxylic acid anhydride; (3) optional monofunctional epoxy resin; (4) a polyfunctional isocyanate resin; and, (5) a polyamine compound containing tertiary amine and either primary or secondary functionality. The reaction product is neutralized in the presence of acid and water to convert the tertiary amine groups to water-dilutable groups. Hydrolyzable silane groups can also be incorporated into the reaction product to further enhance its crater resistance property. The electrocoat composition produces coatings having a smoother appearance with fewer craters without adversely affecting intercoat adhesion of the cured film to subsequent coating layers applied thereover.

Additionally, the compositions can include flatting agents, colored metallic and/or polymeric particles, hard particles, surfactants, rheology modifiers, defoamers, and coalescing aids. The coating composition can be applied to virtually any surface and cured using conventional heat curing techniques, whether or not there is a chemically embossed layer. However, it is advantageously used in surface coverings in combination with a chemically embossed layer. In one embodiment, the surface covering includes a chemically embossed layer and a cured top layer, which are both cured in a single heating step or plurality of heating steps.
