Beschreibung
Zusammenfassung:	Room temperature curing structural adhesive compositions including polyurethane oligomers having multi-methacrylate functionality, cycloalkylmethacrylate, at least one maleimide-functionalized compound and a cure system are disclosed. These compositions exhibit enhanced high temperature properties, including hot strength, heat/humidity strength, and heat aging strength, without compromising initial tensile strength and fixture speeds and still possessing a room temperature cure.
