Abstract
An adhesive composition is provided particularly excellent in thermal shock resistance for adhesive strength as well as high shear adhesive strength, peel adhesive strength and impact adhesive strength. The adhesive composition of the present invention contains (a) a 2-cyanoacrylate such as 2-ethoxyethyl 2-cyanoacrylate and (b) a polyfunctional cyanoacrylate having two or more 2-cyanoacryloyl groups, the number average molecular weight of the polyfunctional cyanoacrylate (b) is in the range from 1,000 to 50,000, and preferably from 2,000 to 30,000, and the content of the polyfunctional cyanoacrylate (b) is in the range from 1 to 400 parts by weight, and preferably from 1 to 200 parts by weight based on 100 parts by weight of the 2-cyanoacrylate (a).
Claims16
An adhesive composition, comprising:
- (a) a 2-cyanoacrylate;
- and
- (b) from 1 to 400 parts by weight, based on 100 parts by weight of the 2-cyanoacrylate, of a cyanoacrylate comprising two or more 2-cyanoacryloyl groups,
- wherein the cyanoacrylate (b) is an ester obtained by reacting 2-cyanoacrylic acid with a polyoxyallsylene polyol, a polyester polyol, a polycarbonate polyol, a polybutadiene polyol, a hydrogenated polybutadiene polyol, a polyisoprene polyol, or a hydrogenated polyisoprene polyol, and
- wherein the number average molecular weight of the cyanoacrylate (b) is in the range from 1,000 to 50,000.
