ABSTRACT:
A process for preparing a chrome substrate for application of a polymer coating, wherein the substrate preparation enhances adhesion and durability of the adhesion between the chrome substrate and the polymer coating, involves contacting the chrome substrate with an acid solution for a period of time sufficient to modify the surface of the chrome substrate. In certain embodiments, the acid treatment is an anodic treatment. In accordance with certain aspects of this invention, the acid treated chrome surface is further treated with a silane compound to enhance adhesion with a subsequently applied polymer coating composition.
