FIELD: chemistry.
SUBSTANCE: invention relates to an adhesive composition, adhesive substance, a product, and a method for forming a bond between two substrates. The adhesive composition includes an epoxide-containing component, a blocked polyisocyanate curing agent, and a latent curing catalyst. The blocked polyisocyanate curing agent is present in the amount from 5 to 50% per the total weight of the adhesive composition. The blocked agent contains a blocking group obtained from a blocking agent containing alpha-hydroxyamide, complex ester or thioester, or a combination thereof. In another option, the blocked polyisocyanate hardener is
.
EFFECT: development of adhesive with impact strength of at least 10 N/mm.
