Abstract
Abstract An adhesive, for a metal, particularly for adhering lead to a polyolefin, contains an addition of 2,5-dimercaptothiadiazole in an amount suitable to act as a complexing agent for the metal so as to create a barrier to prevent acidic scission products formed in the adhesive from reacting with the metal and destroying adhesion.
