Summary: | The invention discloses an aqueous finishing coat. The aqueous finishing coat is composed of a component A and a component B, wherein the component A is composed of the following components by weight percent: 55-85% of aqueous acrylic emulsion, 5-25% of tinting color, 0.5-2.5% of dispersant, 0.5-2% of defoaming agent, 0.5-2% of base material humectant. 0.5-1% of flatting agent, 0.1-0.5% of rheological additive, 0.1-0.5% of catalyst, 0.5-1.5% of light stabilizer and the balance of deionized water; the component B is an aqueous firming agent; and the weight ratio of the component A to the component B is (2-6) to 1. The aqueous finishing coat provided by the invention realizes the aquosity of the finishing cost for a car coating and the amount of the contained harmful substances is obviously reduced; the harmful substances, such as benzene, toluene, dimethylbenzene, ethylbenzene and the like, are not detected; and the content of VOC (Volatile Organic Compounds) is greatly reduced and the content of the free form |
