    摘要: The present invention is directed to a device for process for predicting gloss of a coating resulting from a wet layer of a low gloss coating composition, such as automotive OEM or refinish paint. The device includes measuring reflectance of the layer of the coating composition applied over a test substrate and then allowing the layer to dry and/or cure into a coating. Thereafter, its gloss is measured with a gloss meter. The device is repeated with varying amounts of one or flatting agents added to the composition and the reflectance vs. gloss is plotted on a graph and by using a curve fitting equation a gloss prediction curve is obtained. By measuring the reflectance of a wet layer of a target low gloss coating composition the gloss of a coating that would result from such a layer is then predicted by using the gloss prediction curve. The device is most useful during the manufacture of coating compositions, such as automotive OEM and refinishes paints.

    摘要: Synthetic resins, such as thermoplastics and thermosetting resins, which have certain specified surface resistivities and static dissipation voltage values, are advantageously used as substrates to be coated in electrostatically assisted coating processes. Thus less of an electrically conducting additive, which is often deleterious to the substrate physical properties, may be used and/or additives which do not increase the electrical conductivity of the substrate to much may be used.

    摘要: This invention relates to a method for maximizing the stone chipping resistance and scratch resistance of a multi-layer finish on an automotive substrate. A colored basecoat is applied to the substrate and directly on top of the basecoat is applied a protective clearcoat having a fracture resistance about equal to or above 26 mN and a plastic deformation resistance about equal to or above 30 mN/μm. The resultant coating in addition to being durable to the elements and having excellent appearance produces a finish with an outstanding balance of scratch and stone chip resistance after application.
