Abstract
A method of manufacturing a coated article comprises injecting a feedstock with a polymer resin to provide a resin-injected feedstock, pulling the resin-injected feedstock through a pultrusion die to form a pultrusion substrate having one or more profile surfaces, adhering an adhesive material comprising a thermoplastic polyurethane onto at least a portion the one or more profile surfaces to form one or more adhesive tie layers on the pultrusion substrate, and applying one or more coating materials onto the one or more adhesive tie layers to form one or more coating layers on the one or more adhesive tie layers to provide a coated pultrusion article, wherein an adhesion strength between the one or more coating layers and the one or more adhesive tie layers is higher than a corresponding adhesion strength would be between the one or more coating layers and the pultrusion substrate.
