Latest Patents
Kyohei Homma holds a patent for a "Method for forming multilayer coating film." This patent discloses a method that includes applying a first and second aqueous base coat, along with a clear coat to an object. The process involves simultaneously heating and curing the three-layer coating film. The first aqueous base coat consists of a water-soluble or water-dispersible polyurethane resin with a glass transition temperature of -20°C or below and a weight average molecular weight ranging from 30,000 to 500,000. Additionally, it includes a crosslinkable resin with a weight average molecular weight of 600 or more. The resulting coated film exhibits a breaking strength of 2050 N/cm² or more and a loss tangent (tan δ) at -20°C of 0.075 or more. Notably, the migration amount of a melamine resin from the second aqueous base coat-coated film layer to the first aqueous base coat-coated film layer is limited to within 3% by mass of the total resin solid content of the first aqueous base coat.
