Cyanoacrylate adhesives have existed in the industrial market since the 1990s. Their wide application is due to ease of application, rapid hardening at room temperature, heat resistance and many solvents, as well as strong binding properties of virtually any material.
The production of this adhesive, although is simple in theory, in practice causes some difficulties. Raw materials, i.e. alkyl cyanoacrylate and formaldehyde, are condensed in the presence of an alkaline catalyst. The obtained polymer is then thoroughly dried and thus deprived of the solvent. The main difficulty in this process is the tendency of the monomer to spontaneously polymerize, which affects the drying and further processing of the polymer.
