Method for forming multi-layer film for plastic material and its coated product |
摘要 |
An object of the present invention is to provide a method of coating a plastic material for an automobile in which a transition amount of a polyisocyanate compound from a clear layer to a base layer is larger than a conventional one and that is capable of increasing curability of a base coating while keeping film performance demanded for the clear layer without decreasing water resistance, solvent resistance, and appearance even when a water-based metallic base coating is used. As a means of achieving this object, a coating method of the present invention is a coating method in which three layers of a water-based primer coating, a water-based metallic base coating used for a metal material for an automobile, and a high solid clear coating are simultaneously baked and cured at 70 to 100°C, specific main components in a specific constitution and solvent are used in the high solid clear coating, and the non-volatile part of a two-layer coating film of the primer and base coating is 75% by weight or more when the high solid clear coating is applied.
