Abstract
A coated product having at least four coating layers comprising an undercoating layer formed by coating an undercoating material containing a fluorocarbon resin powder and an aromatic resin and having a viscosity of from 20 to 500,000 poise, an intermediate coating layer formed by coating an intermediate coating material containing a fluorocarbon resin powder and an inorganic pigment and having a viscosity of from 20 to 500,000 poise and a topcoating layer formed by coating a topcoating material containing a fluorocarbon resin powder and having a viscosity of from 20 to 500,000 poise, wherein the fluorocarbon resin powder in each coating layer has an average particle size of 0.1 to 40 .mu.m.
Claims5
A coated product having at least four coating layers comprising a metal substrate having a flat smooth surface, that has not been subjected to roughening treatment, coated by an undercoating layer formed by coating an undercoating material having a viscosity of from 20 to 500,000 poise containing a fluorocarbon resin powder and an aromatic resin, at least two intermediate coating layers formed by coating at least two intermediate coating materials having a viscosity of from 20 to 500,000 poise containing a fluorocarbon resin powder and an inorganic pigment and a topcoating layer formed by coating a topcoating material having a viscosity of from 20 to 500,000 poise containing a fluorocarbon resin powder, said fluorocarbon resin powder in each coating material having an average particle size of from 0.1 to 40 .mu.m and each of said coating layers being formed by screen-printing.
