  • Patent number: 5536799
    Abstract: A cyanoacrylate adhesive composition, which contains esters in which an alcohol residue thereof includes a dipentaerythritol residue and an acid residue thereof is an acrylic or methacrylic acid residue, and which composition is improved in adhesion performance under high temperature and humid conditions, namely moisture and thermal resistance. The cyanoacrylate adhesive composition according to the present invention has excellent moisture and thermal resistance and thus is more widely usable than conventional ones in various industries, medical field, and leisure activity as well as household application and pupils' stationary.
