Provided is a coating material composition that does not use N-methyl-2-pyrrolidone and has the same performance as conventional ones. The coating material composition contains polytetrafluoroethylene, a polyamideimide resin, and a filler, and being substantially free of N-methyl-2-pyrrolidone, wherein the filler has a hardness of 7 to 12 on a new Mohs hardness scale and a primary particle size of 1 μm or less, wherein the content of the filler is 10 to 30 parts by mass relative to 100 parts by mass of a solid content of the polyamideimide resin in the coating material components, wherein the coating material composition has a viscosity of 10,000 to 20,000 cps, and wherein a degree of dispersion of the coating material as measured according to JIS K5600 with a grind gauge is 5 μm or less.
A coating material composition comprising polytetrafluoroethylene, a polyamideimide resin, a filler and at least one solvent selected from the group consisting of N-ethyl-2-pyrrolidone, 3-methoxy-N,N-dimethylpropaneamide, and N-butyl-2-pyrrolidone, and being substantially free of N-methyl-2-pyrrolidone,
