Polycarbonate system having enhanced weatherability and method of making same

摘要

A polycarbonate system having enhanced weatherability is disclosed. The polycarbonate system comprises a substrate comprising a first surface and a second surface, a primer disposed on the first surface of the substrate, and a top coat disposed on the primer on the first surface for abrasion resistance. At least one of the primer and the top coat comprises an ultraviolet absorber in a solvent for ultraviolet absorption, the ultraviolet absorber having an extinction coefficient of >=45,000 L-mol^-1 cm^-1 at lambda=325 nm.
