Abstract:
An ultraviolet light absorber (UVA) Universal Composition powder coating is provided. The composition can include about 73.0 to about 78.0 weight percent (wt. %) of a silicone resin, about 2.0 to about 7.0 wt. % of a hardener, about 0.7 to about 1.2 wt. % of a UV stabilizer, about 0.7 to about 1.2 wt. % of a flow modifier, about 15.0 to about 20.0 wt. % of a glass flake, and about 0.1 to about 0.6 wt. % of a catalyst. A UVA additive composition including a plurality of UVA additive particles having a continuous phase of a silicon resin that contains a hardener, a UV stabilizer, a flow modifier, glass flakes, and a catalyst, wherein the plurality of UVA additive particles have a particle size of 0.5 to 100 μm, is also provided.
