Abstract
Metal fastener sticks wherein the individual fastening elements, such as staples, on the stick are secured together by a radiation cross-linked polymer, and which metal fastener stick is prepared by: coating the metal fastener stick with a solventless, radiation -curable, polymeric composition, such as an ultraviolet-curable formulation of an unsaturated resin, a monomer and a photo initiator; and curing the composition by exposing the composition to radiation, such as ultraviolet radiation, to provide a metal fastener stick wherein the individual fastener elements are secured together in the stick through the radiation cross-linked polymer.
