1. A system for improving the corrosion resistance of an exterior weatherable powder coating, comprising a powder formulation, the formulation comprising
a TGIC-reactive polymeric binder; and about 1 to 10 wt % of a saturated, high molecular weight (Mn) non-reactive polyester, based on the total weight of the formulation, wherein corrosion resistance of a cured coating formed from the formula is improved by 40% over a standard powder coating, when subjected to cyclic corrosion testing. |
