Abstract:

The present invention is directed to dirt and anti-microbial resistant compositions and articles that include a powder coating composition formed from a precursor comprising polymeric binder resin, cross-linker, and a blend of liquid carrier and anionic fluorosurfactant. The powder coating may be formed using a liquid-based anionic fluorosurfactant wherein the solids content of the anionic fluorosurfactant within the precursor is from about 13 wt. % to about 28 wt. %.
