  • Patent number: 10214654
    Abstract: Provided is a method for forming a multilayer coating film, said method being suitably applicable to a wet-on-wet coating process comprising: applying a first water-borne base coating material to form an uncured first water-based base coating; and then applying a second water-based base coating material without preheating the uncured first water-borne base coating. A method for forming a multilayer coating film according to a wet-on-wet coating process which comprises applying a first water-based base coating material to the surface of a substrate to be coated and then applying, without preheating the thus formed coating, a second water-based base coating material, characterized in that: the first water-borne base coating material contains a hydrophilic association-type viscous material; and the composition of the second water-based base coating material is controlled.

  • Patent number: 9393592
    Abstract: The present invention discloses a process for forming a multiple layered coating film in three wet coating method, which the multiple layered coating film has excellent chipping resistance while maintaining smoothness between the coating films. The present invention provides a process for forming a multiple layered coating film comprising the steps of forming an uncured first base coating film; an uncured second base coating film and an uncured clear coating film in order on an automobile body having an electrodeposition coating film on the surface thereof, and then simultaneously heating and curing the uncured coating films to form a multiple layered coating film, wherein the multiple layered coating film comprising the first base coating film having the dry coating film thickness of 25 ?m, the second base coating film having the dry coating film thickness of 10 ?m and the clear coating film having the dry coating film thickness of 30 ?m has an elongation at 20° C.
