Abstract:
An adhesive article is described comprising a foamed adhesive layer and a non-foamed adhesive layer. The adhesive of each adhesive layer comprises a tetrahydrofurfuryl (meth)acrylate copolymer; an epoxy resin; a polyether polyol; and optionally a hydroxy-functional film-forming polymer. The adhesive may be used in structural and semi-structural bonding applications and is designed to fail cohesively.
