A method of packaging a battery device with a metal shell, comprising: applying a waterborne two-component polyurethane composition to the metal shell of the battery device, and drying the applied polyurethane composition to form a packaging layer; wherein the polyurethane composition comprises, (A) an aqueous dispersion comprising a hydroxyl-functional polymer, wherein the hydroxyl-functional polymer comprises, by weight based on the weight of the hydroxyl-functional polymer, from 20% to 50% of structural units of a hydroxy-functional alkyl (meth)acrylate; from 0.1% to 10% of structural units of an acid monomer, a salt thereof, or mixtures thereof; and structural units of a monoethylenically unsaturated nonionic monomer; and (B) a polyisocyanate.

A method for forming a multilayer coating film comprising the steps of: (1) applying a base paint (X) to a substrate to form a base coating film, (2) applying an effect pigment dispersion (Y) to the base coating film formed in step (1) to form an effect coating film, (3) applying a clear paint (Z) to the effect coating film formed in step (2) to form a clear coating film, and (4) heating the uncured base coating film, the uncured effect coating film, and the uncured clear coating film formed in steps (1) to (3) to thereby simultaneously cure these three coating films; wherein the effect pigment dispersion (Y) contains water, a black pigment (A), a vapor deposition metal flake pigment (B), and a rheology control agent (C).

A two-component polyurethane coating composition is described. The composition includes a multifunctional isocyanate component and a multifunctional polyol component. The polyurethane described herein is an overindexed composition that may be used as a tiecoat in a conventional recoat or refinish process. The described composition provides improved adhesion between an aged coat and a newly applied coating.

The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.

A method of locating a defect in an e-coat on a surface can include acquiring an image of the surface. A correction coefficient can be applied to the image to form an adjusted image. The correction coefficient can relate pixel values of the image to a calibration value. The adjusted image can be separated into a spectral component which can be modified by a block average determination to create a modified spectral component. The spectral components can be compared with the modified spectral components to form a difference image. The difference image can be dilated and eroded. A region of interest can be identified from an image region using a blob detection. The defect can be classified as a defect type. The defect can be repaired or a coding parameter can be altered based on the defect.
