Coating reinforcement application and method

摘要

A method for applying a polymer to a substrate having a first surface and a second surface (such as an inside surface and outside surface). One or more apertures are provided through the substrate, with the apertures linking the first and second surfaces. A polymer coating is applied to the first and second surfaces, with some of the polymer coating flowing into and remaining within the aperture(s). The polymer coating within the aperture(s) serves to link the polymer coating covering the first surface and the polymer coating covering the second surface. The invention also encompasses coated objects made using the inventive method.

主权项

1. A method for coating a substrate, comprising:
a. providing a substrate, having a first surface and a second surface, wherein said first surface and said second surface are separated by a thickness of said substrate; b. said first surface having an original surface area; c. providing a plurality of apertures connecting said first surface to said second surface, wherein the presence of said plurality of apertures reduces said original surface area to a net surface area; d. said net surface area being at least fifty percent of said original surface area; e. providing a polymer having a melting temperature, wherein said polymer is capable of transitioning from a liquid state to a solid state; f. heating said substrate above said melting temperature of said polymer; g. spraying said polymer onto said second surface; h. spraying said polymer onto said first surface; i. wherein said heated substrate melts said polymer and some of said liquid polymer on said first surface flows into said apertures and adheres to said polymer on said second surface; and j. allowing said liquid polymer to solidify, so that said polymer on said first surface, said second surface, and in said apertures is linked together as a solid.
