Claim:
A stock material for use in the assembly of apparatuses, devices or articles of manufacture which stock material is in a finished or semi-finished state and has one or more surfaces that are to be bonded or fastened to itself or other components of the apparatus, device or article of manufacture during the assembly thereof wherein at least a portion of said one or more surfaces has applied thereto a substantially dry-to-the-touch, pre-applied, curable adhesive composition comprising an encapsulated liquid curable material and a separately encapsulated curative complex, said curative complex being encased in a polymer capsule and comprising an in-situ formed carrier material and an effective amount of a curative or combination of curatives contained in the carrier material and capable of effecting, directly or indirectly, the cure of the aforementioned liquid curable material, said carrier material being a natural or synthetic material or composition that is substantially non-flowing in the absence of external forces, elevated temperatures or both impacting upon said curative complex wherein the in-situ formed carrier material is formed concurrent with or subsequent to the encapsulation of the curative complex by the action of a curative with or on a precursor composition for said carrier material and either (i) the curative for the in-situ formed carrier material is different from and in addition to the curative contained in said carrier material or (ii) the curative for the in-situ polymerized carrier material is the same as the curative contained in the carrier and the amount of the curative prior to in-situ polymerization of the carrier material is at least 1.6 weight % based on the weight of the carrier material and the amount of curative remaining after polymerization of the carrier material is effective for effecting cure of the liquid curable material.
