Abstract:
A powder coating composition comprising composite powder particles that are an agglomerate of individual particulate components fused or bonded together, wherein the size distribution of the agglomerated particles is up to 120 &mgr;m, with a Dv.50 within the range of from 15 to 75 &mgr;m, and wherein the individual particulate components comprise(1) one or more colored film-forming base components having a Dv.99 of no more than 30 &mgr;m, and (2) one or more uncolored film-forming components, wherein at least one of the uncolored film-forming components is an uncolored film-forming component (2a) that (i) has a Dv.99 that is more than 20 &mgr;m and (ii) has a higher Dv.99 or higher Dv.50 than the one or more colored film-forming base components (1) taken together, wherein the ratio of the one or more colored film-forming base components to the one or more uncolored film-forming components in the composition is in the range of from 1:99 to 60:40 by weight.
