| 摘要 |
The present invention is directed to an aqueous coating composition, comprising: a) an aqueous nonionic dispersion of a polymer selected from the group consisting of a acrylic resin, polyurethane resin and mixtures thereof; b) a nonionic water soluble polymer having a molecular weight of from about 3,000 to about 200,000 daltons; c) pigments; and d) optionally additives selected from the group consisting of crosslinkers, organic solvents, surfactants, rust inhibitors, catalysts, and mixtures thereof. The new aqueous coating composition is stable in the presence of acids and bases especially with the cure of crosslinkers.
