摘要： PROBLEM TO BE SOLVED: To provide a method for forming a combined layer coating film capable of forming the combined layer coating film comprising a cation electrodeposition coating film layer and an intermediate coating film layer by one heating/ curing step without generating a problem, i.e., a reduction of rust-resistance. SOLUTION: This method for forming the combined layer coating film comprises a step (1) for coating an object to be coated with a cation electrodeposition coating material and forming an electrodeposition uncured coating film without heating/curing; a step (2) for coating the electrodeposition uncured coating film formed by the step (1) with a water base intermediate coating material to form an intermediate uncured coating film; and a step (3) for simultaneously heating/curing the combined layer uncured coating film formed by the step (1) and the step (2). In the combined layer coating film formed by the above formation method, a temperature T adopting a peak value derived from Tg of the cation electrodeposition coating film among peak values of tanδ measured by a dynamic viscoelasticity measurement is 110°C-140°C.

摘要： PROBLEM TO BE SOLVED: To provide a top clear coating method for an automobile body capable of efficiently forming a top clear layer excellent in flatness.
SOLUTION: A control circuit 15 controls a flow rate Qfm of suction air by adjusting a pressure regulator 12 for suction air such that a feed amount Qp of a fine particle coating material F measured by a powder flow rate measurement device 7 becomes a set feed amount Qm and adjusts a pressure regulator 13 for dilution air such that a flow rate Qt of conveying air i.e., a sum of the flow rate Qfm and a flow rate Qfs of the dilution air becomes constant. The fine particle coating material F having an average particle diameter of 10-25 μm fed to a coating gun 5 is pulse-charged by a corona discharge generated by applying a pulse-like high voltage from a pulse voltage generation device 6 to a corona electrode of the coating gun 5 and is coated on a surface of the automobile body.
