A Heat-Resistant Film Adhesive on the Basis of Cyane Ethers

Abstract A film adhesive based on dicyanoether of diphenylolpropane and polysulfone has been developed. The strength characteristics of the film have been studied. The operability of the resulting adhesive joints up to a temperature of 230°C with high strength is shown. The dependence of the glass-transition temperature of the cured adhesive on the curing temperature has been studied. The presence of a certain water resistance of the adhesive joint and the cured adhesive has been shown.
