  • Publication number: 20210340400
    Abstract: The present invention addresses the problem of providing a painted metal plate having rain-streak-stain resistance and a good appearance, and a method for producing the same. To solve this problem, the method for producing a painted metal plate includes a step for forming a coating by applying a paint containing a silicone resin and a fluorine-containing resin to the surface of a metal plate and curing the paint, and a step for performing flame treatment on the coating. The silicone resin contains 5 to 50 mol % of a silanol group with respect to the total molar mass of Si atoms.
