Partially coated fastener assembly and method for coating

摘要

A fastener assembly (50) includes a row of fasteners (49) having a head (51), a tip (47), and a portion of a shank (48) 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 (50) is coated with the polymer composition by vacuum (111, 108, 112) coating (120, 106, 114) a dispersion of the polymer composition in a solvent such as water and removing the solvent.
