Abstract

It is shown that the use of EP-0234 epoxy primer, used as an adhesive sublayer under VK-36 epoxy-polysulfone adhesive leads to an increase in the holding time between the process of chemical oxidation in chromic acid (An.Ox.chrome) of the glued surfaces of aluminum alloys and the start of technological bonding work for up to 30 days (instead of 2 days for anodized surfaces without primer) without deterioration of the glued samples, and in some cases – to their improvement.
