Abstract
An example device housing comprises a substrate, and a topcoat layer including a topcoat formulation disposed on a surface of the substrate. The topcoat formulation includes a polymer, a pigment including zirconium dioxide nanoparticles present in an amount ranging from about 0.3 weight percent to about 5 weight percent of a total weight of the topcoat formulation, and a balance of water.
