The Chemical Resistance of Adhesive Bonds Based on Epoxy Urethan Oligomers Synthesized Using Different Diisocyanates

The dependence of adhesive strength of adhesive bonds of steel of grade St3 obtained using oligourethane diepoxides and short-chain aliphatic amine on the time of exposure in various chemical liquids such as water solutions of chemical reagents and oil products was considered. It was shown that the impact of the latter changes the nature of separation of adhesive bond.
