Abstract

Reviewed the performance of adhesive joints made of epoxy film adhesives VK-31, VK-41 and MC-51, while the impact of conditions of warm humid climate of Black sea coast and loads of 0.2–0.5 of the original strength of the adhesive joints. It is shown that the level of remaining strength after exposure to the above conditions affects not only the initial strength of the adhesive joints, but also the temperature at which the curing of the adhesive. Adhesive bonding for all three adhesives showed a high level of retained strength after exposure to climatic conditions of warm moist climate of Black sea coast and loads.
