Abstract:
A method for the fabrication of a cyanoacrylate adhesive so as to minimize the presence of contaminants and extraneous additives in the resulting cured adhesives and enhancing the cure speed of stabilized cyanoacrylate adhesive by a treatment that removes excessive stabilizers prior to application onto a substrate, the method comprising the steps of (a) providing a stable adhesive composition comprising cyanoacrylate adhesive and a stabilizing agent to produce a cyanoacrylate adhesive composition, (b) presenting a substrate to receive at least a portion of the cyanoacrylate adhesive composition and (c) applying the cyanoacrylate adhesive composition to the substrate,the improvement comprising the step of removing stabilizing agent from the cyanoacrylate adhesive composition prior to the step of applying, wherein the step of removing stabilizing agent from the cyanoacrylate adhesive composition consists essentially of contacting the cyanoacrylate composition with a particulate agent and subsequently isolating the particulate agent and the stabilizing agent from the cyanoacrylate adhesive via an isolation process.
