Abstract

Provided are a chromium-free fluoropolymer-containing primer composition, which can provide a coated article having excellent higher corrosion resistance by forming a fluoropolymer coating film, and a primer layer having sufficient adhesive strength to the fluoropolymer coating film on the surface of a substrate such as metal, glass, ceramic and heat resistant plastics, a method for manufacturing a coating film using the same, and a coated article using the same. The coating composition contains at least one kind of a fluoropolymer component selected from a reactive functional group-containing fluoropolymer, and a fluoropolymer having a melt flow rate (MFR), measured under a load of 5 kg and at 372° C., in accordance with ASTM D1238, of 10 to 100 g/10 minutes, and an organic titanate, wherein content of titanium contained in the organic titanate, relative to the fluoropolymer component, is 1 to 40% by weight.
