Title:
METHOD FOR FORMING MULTI-LAYERED COATING FILM
Document Type and Number:
WIPO Patent Application WO/2011/132551
Kind Code:
A1
Abstract:
The disclosed method for forming a multi-layered coating film comprises the sequential execution of: a step for applying an intermediate coating material onto an object to be coated, forming an intermediate coating film; a step for applying an aqueous base coating material onto said intermediate coating film, forming a base coating film; a step for applying a clear coating material onto said base coating film, forming a clear coating film; and a step for simultaneously curing the formed uncured intermediate coating film, base coating film, and clear coating film by means of heating the three coating films. At 40°C under the conditions of a shear stress of 1.0 Pa and a frequency of 0.1 Hz, the intermediate coating material has a complex viscosity (η*40) of no more than 100 Pa·sec, and at 80°C under the conditions of a shear stress of 1.0 Pa and a frequency of 0.1 Hz, has a complex viscosity (η*80) of at least 800 Pa·sec.
