Abstract
A fastener assembly includes a row of fasteners having a head, a tip, and a portion of a shank coated with a polymer composition. The polymer composition includes a polymer material such as polyurethane and metal particles. The polymer composition is used to provide improved corrosion and ultraviolet radiation resistance when used with naturally corrosive or pressure preservative treated wood. The fastener assembly is coated with the polymer composition by vacuum coating a dispersion of the polymer composition in a solvent such as water and removing the solvent.
