ABSTRACT:
There are here disclosed an adhesive composition obtained by adding a fluorine-containing carboxylic acid epoxy adduct to a 2-cyanoacrylate, and a process for preparing the adhesive composition. This 2-cyanoacrylate-based adhesive composition is excellent in storage stability and particularly excellent in adhesive force and impact resistance and has a high hardening rate. In particular, the adhesive strength of the 2-cyanoacrylate-based adhesive composition can be remarkably increased without lowering the hardening rate, and so the 2-cyanoacrylate-based adhesive composition can exert a sufficient resistance to impact and the like at the time of the adhesion of metals, rubbers, plastics and lumbers and the reliability of adherends can be improved.
