Abstract: A powder slurry coating composition is prepared by adding individual particulate materials including at least one resin powder to an aqueous medium and then milling the dispersed particulate materials to produce a median particle size of up to about 15 microns. The powder slurry coating composition is used to prepare a coating on a substrate. The coating is equivalent to coatings obtained from powder slurry coating compositions in which the powder is produced by melt mixing in an extruder and grinding the extrudate.

Abstract: The invention provides a method for improving the adhesion of a repair coating to a coated substrate. It requires that at least one coating composition be applied to a substrate, the coating composition having (a) a film forming component with (i) a crosslinking component comprising one or more aminoplast resins, and (ii) one or more polymers having one or more functional groups which are reactive with the crosslinking component, (b) an adhesion improving additive comprising one or more compounds containing Sn(IV), (c) a catalyst for promoting a reaction between crosslinking agent (i) and one or more polymers (ii). The at least one coating composition is cured to provide a coated substrate and one or more repair coatings are applied to the coated substrate. In a preferred aspect of the invention, the one or more repair coatings applied are the same as the at least one coating composition.
