ABSTRACT:
A fluororesin-coated article having excellent corrosion resistance is disclosed, which comprises a base plate having a finely roughened surface and having thereon a layer of a fluororesin composition containing a fluororesin comprising a mixture of a heat-fusible fluororesin and PTFE, the content of the heat-fusible fluororesin in the mixture being 2% by weight or more but less than 12% by weight based on the total amount of the fluororesin. The fluororesin composition layer may contain an inorganic pigment in an amount of 1 to 25% by weight based on the total amount of solid components of the composition. A fluororesin-coated article free of pinholes in its coatings is also disclosed, which comprises a base plate having thereon a fluororesin coating and further thereon a surface layer containing substantially no pigment and adhesion aid and comprising a mixture of a heat-fusible fluororesin and polytetrafluoroethylene, the content of the heat-fusible fluororesin being 2% by weight or more but less than 12% by weight based on the total amount of the mixture.
