1. A substrate at least partially coated with a curable coating composition, the curable coating composition comprising:
(a) a binder comprising:
(i) a film-forming resin comprising at least two functional groups; and
(ii) a curing agent reactive with the functional groups of (i); and
(b) solid vulcanized rubber particles unreactive with any other component included in the curable coating composition, wherein the solid vulcanized rubber particles have a glass transition temperature (Tg) of less than −40° C.,
wherein the solid vulcanized rubber particles have an average particle size of from 10 to 85 microns,
wherein the curable coating composition is a solid particulate powder coating composition,
wherein the solid vulcanized rubber particles are not a component of a core-shell structure formed by reaction within the curable coating composition,
wherein the solid vulcanized rubber particles are crosslinked through sulfur bonds,
wherein the curable coating composition comprises from 1 weight % to 40 weight % of the solid vulcanized rubber particles, based on the total solids weight of the coating composition, and
wherein a coating layer formed from the curable coating composition has a dry film thickness of 300 to 800 microns.
