Abstract
A one-component toughened epoxy-modified polyurethane and/or urea adhesive includes a mixture of dicyandiamide and a dihdyrazide as curing agents. The mixture of curing agents permits the adhesive to be cured at lower temperatures while developing good adhesive and mechanical properties in the cured adhesive.
