  • Adjustable hybrid PSA/structural adhesive bonds by patterned surface-initiated cure
    Patent number: 12247145
    Abstract: Articles comprising, in order: a first adherend, a first primer layer, an adhesive layer, and a second adherend are provided, where the adhesive layer comprises pressure sensitive adhesive domains and structural adhesive domains. Typically, the first primer layer covers first portions of the first adherend adjacent to structural adhesive domains and does not cover second portions of the first adherend adjacent to pressure sensitive adhesive domains. Methods of making such articles are provided, which comprise applying a cure-initiating primer to first portions of the first adherend to form a first primer layer while leaving second portions of the first adherend bare of the first primer layer, and thereafter applying a curable adhesive film over the first primer layer, such that portions of the curable adhesive film are cured to form structural adhesive domains and other portions remain uncured pressure sensitive adhesive domains.
