Abstract

A coating method for a clad steel in which stainless sheets are combined on adjacent surfaces of an aluminum sheet may include preparing the clad steel, preparing a coating solution in which an epoxy resin and titanium dioxide (TiO2) powder are combined in an acrylic resin, etching the clad steel to improve adhesion property between the coating solution and the clad steel, heating the clad steel, and performing electrodeposition by immersing the clad steel in the coating solution.

First claim

What is claimed is:

1. A coating solution for coating a clad steel comprising in percent by weight (wt %), acrylic resin of 40 to 50%, TiO 2 of 10 to 15%, epoxy resin of 10 to 15%, melamine curing agent of 10 to 20%, aromatic solvent of 5 to 10%, and cyclohexanone of 10 to 15%.
