Title:
Double layer film formation method
Document Type and Number:
Japanese Patent JP6208120
Kind Code:
B2
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 μm, the second base coating film having the dry coating film thickness of 10 μm and the clear coating film having the dry coating film thickness of 30 μm has an elongation at 20° C. of 40 to 60%, a tensile strength at 20° C. of 400 to 600 kgf/m2 and a ratio of viscous term to elastic term (tan δ) at −20° C. of 0.04 to 0.06.
