PROBLEM TO BE SOLVED: To provide a two-part hybrid adhesive with good stability, high adhesion to untreated plastic substrates, and good processing characteristics in conventional equipment.SOLUTION: A polymerizable adhesive composition contains an organoborane amine complex and a polyamine with a nitrogen-to-boron atomic ratio of less than 4, a polyisocyanate component, and a free radically polymerizable component, and contains substantially no polyol. A two-part polymerizable adhesive composition contains an organoborane amine complex, a polyamine component, a free radically polymerizable component, and a polyisocyanate. A two-part hybrid adhesive contains the composition with more than 40 wt.% of the polyisocyanate in a second part (B). |
