Multifunctional coatings for fasteners

摘要

A coating composition adapted for application on a fastener, the coating composition composed of a binder component composed of a polymeric resin present in the composition at a concentration between 1.0% and 15.0% by total composition weight, wherein the binder component is composed of at least one of a solvent dispersible compound; a reactive cross-linking component present in the composition in an amount between 1.0% and 80.0%; at least one curing agent; optionally at least one expansion agent, wherein at least one of the curing agent or the reactive cross-linking component are physically and reactively isolated from other components of the composition.

1. A fastener comprising:
an elongated body; a head joined with the body, each of the head and body having an outer surface, at least one of the elongated body and the head including a coating composition disposed in overlying layered relationship relative to a least portion of the outer surface, the coating composition comprising: a binder component composed of a polymeric resin present in the composition at a concentration between 1.0% and 30.0%, inclusive, by total composition weight, wherein the binder component is composed of at least one solvent dispersible compound, and wherein the polymeric resin includes at least one of acrylic copolymers and terpolymers, thermoplastic polyurethanes, thermoplastic elastomer, and acrylic or vinyl polymer or copolymer dispersions; a reactive cross-linking component present in the composition in an amount between 1.0% and 80.0%, inclusive, by total composition weight; at least one curing agent; and an expansion agent isolated from the binder component, the reactive cross-linking component and the at least one curing agent, wherein at least one of the curing agent and the reactive cross-linking component are present in the composition in a position isolated from at least one of the binder component and one another.
