Abstract: A single component curable composition is provided that includes a resin curable by free radicals. Free radicals are initiated by the inclusion of at least one photo-initiator, at least one thermal radical initiator, and at least one thermal cationic radical initiator, all present in a premixed state as the single component. The composition is able to cure to a depth beyond the penetration of photons into composition. Once cure is initiated with an ultraviolet or infrared light source, the light source need not illuminate the composition until cure is complete. The resulting composition has a user selected working time that is effectively infinite and the viscosity stable while working prior to initiating cure. A method for repairing a surface imperfection on a vehicle body is also provided along with a novel cured mass with a thickness of up to 7 mm.
