Abstract
Abstract A fluororesin coating composition comprising a liquid medium having dispersed therein (A) fluororesin particles having an average particle diameter of 5 µm or more and (B) fluororesin particles having an average particle diameter of 1 µm or less. In the coating composition, the proportion of the fluororesin particles (B) based on the total amount of the fluororesin particles (A) and (B) being from 20 to 80% by weight. The fluororesin coating composition is excellent in both film-forming properties and stability.
