Abstract
A water-dispersed powder slurry coating comprises: (A) a particulate comprising (a1) a resin having an active hydrogen; (B) a reactive surfactant having an optionally blocked isocyanate group and/or an epoxy group; and an aqueous medium in which the particulate and the reactive surfactant are contained. The powder slurry coating can provide a film excellent in water resistance and strength. The powder slurry coating can be baked at a lower temperature and provide a film excellent in resistance to acid rain.
Claims18
A water-dispersed powder slurry coating, comprising:
- (A) a particulate comprising (a1) a resin having an active hydrogen;
- (B) a reactive surfactant having at least one of an optionally blocked isocyanate group and an epoxy group;
- (M) an aqueous medium in which said particulate and said reactive surfactant are contained;
- (a2) a curing agent;
- and
