A method for dispensing an acidic conversion coating comprising introducing through a port in a reservoir chamber of a hand-held applicator an aqueous conversion coating composition that exhibits a pH within the range of 1.5-4.5 and includes O.OOOl-3% by volume of an acid stable fluorinated surfactant; and closing the port with an applicator wick, wherein the conversion coating composition can be dispensed from the reservoir through the wick.
POWDER COATINGS
U.S. Patent 6,207,768. Mar. 27, 2001 Y. Sato et al., assignors to Kao Corp., Tokyo
A combination of powder coatings usable in a coating method comprising mixing two or more powder coatings of which each color is different, wherein each of the powder coatings does not have thermosetting properties alone at a temperature of 250°C or less, each of the powder coatings comprises a resin having two or more functional groups per molecule; each of the two or more powder coatings heat-cure when mixed with each other at a temperature of 250°C or less, wherein heatcuring is a result of two or more powder coatings reacting with each other, thereby providing a coating film having a homogeneous hue.
