Abstract
Abstract A padeye fastening assembly for attachment to a surface, having an eye or ring affixed to a disc, and having cemented to the disc a plurality of microcapsules containing the constituents of a two-part polyester epoxy adhesive system. The microcapsules are protected from being removed during handling by a disposable cap. The padeye is secured to the desired place by pressing and wringing it against the surface, thereby crushing the shells of the capsules, mixing the constituents, and maintaining contact until curing takes place.
