Room temperature curing structural adhesive compositions including polyur ethane oligomers having multi-methacrylate functionality, cycloalkylmethacry late, at least one maleimide-functionalized compound and a cure system are d isclosed. These compositions exhibit enhanced high temperature properties, i ncluding hot strength, heat/humidity strength, and heat aging strength, with out compromising initial tensile strength and fixture speeds and still posse ssing a room temperature cure.
