A coating material includes a first aqueous dispersion (A) and a second aqueous dispersion (B) wherein a dispersoid of the first aqueous dispersion (A) has an average particle diameter of 1 to 20 &#x3bc;m and a dispersoid of the second aqueous dispersion (B) has an average particle diameter 1/100 to &#x2155; of that of the dispersoid of the first aqueous dispersion (A), and the mass ratio (the aqueous dispersion (A)/the aqueous dispersion (B)) of the dispersoid of the first aqueous dispersion (A) to the dispersoid of the second aqueous dispersion (B) is 2/1 to 100/1. Also provided is a container, which is coated with the coating material and has excellent properties.

Coating material and container coated with the coating material

A method of forming a coating on an inner periphery of a tube with a cylindrical barrel, a mouth on one axial end of the barrel, and a shoulder located between the barrel and the mouth. The method involves holding the tube, and subsequently jetting powder into the tube from a spray gun, through a bottom side opening on the other axial end of said barrel. A first passage guides to the spray gun a first air stream together with the powder. A second passage feeds to the spray gun a second air stream with the powder. A third passage suction collects surplus powder through the tube mouth. A fourth passage suction collects surplus powder through the bottom side opening of the tube. At least one of the passages is subject to a feedback control such that flow rate and/or internal pressure therein are maintained at target levels.
