COATING SYSTEM AND METHOD
First Claim
1. A method of manufacturing a coated article, the method comprising:
- 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 one or more adhesive materials 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.

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 one or more adhesive materials 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.

8. A pultrusion system comprising:
-
a resin-injection assembly to inject a feedstock with a polymer resin to provide a resin-injected feedstock; a pultrusion die to shape the resin-injected feedstock into a pultrusion substrate having one or more profile surfaces; and a coating system comprising; an adhesive-application assembly to apply one or more adhesive materials onto at least a portion of the one or more profile surfaces of the pultrusion substrate to form one or more adhesive tie layers, and a coating-material application assembly to apply one or more coating materials onto the one or more adhesive tie layers to form one or more coating layers in order to provide a coated pultrusion article. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A coated article comprising:
-
a composite substrate formed from a reinforcing feedstock at least partially embedded in a matrix polymer, the composite substrate including a center portion and a peripheral portion at least partially surrounding the center portion, the peripheral portion having a greater concentration of the matrix polymer than the center portion; one or more adhesive tie layers disposed along at least a portion of the peripheral portion of the composite substrate; and one or more coating layers disposed above the one or more adhesive tie layers, the one or more adhesive tie layers providing an adhesive interface between the composite substrate and the one or more coating layers, 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 peripheral portion of the composite substrate. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
