摘要 |
A coating method is a method for forming a multilayer coating film including at least one lower layer formed on a substrate and an uppermost layer formed on the lower layer, and the coating method comprises the steps of: preparing a certain curable coating material as an uppermost layer-coating material for forming the uppermost layer, and preparing a certain coating material as at least one lower layer-coating material for forming the lower layer; forming an uncured multilayer coating film by applying the lower layer-coating material and the uppermost layer-coating material on the substrate using a wet-on-wet technique; and curing at least the uppermost layer-coating material by subjecting the uncured multilayer coating film to a curing treatment. |

1. A coating method for forming a multilayer coating film including at least one lower layer formed on a substrate and an uppermost layer formed on the lower layer, the coating method comprising the steps of:
preparing a noncurable coating material as at least one lower layer-coating material for forming the lower layer of the multilayer coating film; preparing a thermosetting coating material as an uppermost layer-coating material for forming the uppermost layer of the multilayer film, wherein the noncurable coating material is a coating material having a weight loss percentage of 0.5% by mass or less at a curing temperature of the uppermost layer-coating material; forming an uncured multilayer coating film by applying the lower layer-coating material and the uppermost layer-coating material on the substrate using a wet-on-wet technique; and curing at least the uppermost layer-coating material by subjecting the uncured multilayer coating film to a heat treatment wherein the noncurable coating material undergoes no curing reaction by the heat treatment. |
