A process for repairing a vehicle body includes mixing the part A with the part B to form a mixture. The mixture is applied to a substrate of the vehicle body in need of repair. Upon curing to form a fill, the vehicle body is repaired and the fill is a sandable surface.

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.

Abstract: A method for repairing small surface imperfections on a vehicle body is provided that includes the application of an uncured layer to a thickness of up to 1.02 mm of a composition inclusive of a polyester resin, an acrylated urethane resin, a defoamer, and a particulate filler to the vehicle body or a cured putty thereon. The uncured layer is then exposed to actinic radiation to induce cure of the uncured layer to form a coating to fill the small surface imperfection on the vehicle body. A one component, UV-cured putty material for repairing small surface imperfections is also provides inclusive of a polyester resin, an acrylated urethane oligomer or polymer, a defoamer, a photoinitiator, and a particulate filler. The composition has an uncured viscosity of between 9,000 and 13,000 centiPoise.

Abstract: A method for repairing surface imperfections on a vehicle body includes the application of an uncured layer to a thickness of up to 0.254 mm of a primer composition comprising: a polyester resin, an acrylated urethane resin, a crosslinking agent, a solvent, and a particulate filler to the vehicle body. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a coating to fill the surface imperfection on the vehicle body. A surface coating primer composition is also provided that includes a polyester resin; an acrylated urethane oligomer or polymer; a crosslinking agent; a solvent; a photoinitiator; and a particulate filler. The uncured composition has a viscosity of between 100 and 800 centipoise.

The part A includes phenolic epoxy resin, polyol epoxy resin, or lipid epoxy resin, or a combination thereof. The part B includes a curing agent of only an aliphatic amine, a phenalkamine, a phenalkamide, or a combination thereof, to form a mixture. The mixture is applied to a substrate of the surface in need of repair to a thickness of up to 6.35 mm. The mixture cures on the substrate under conditions adapted to a dry to sand condition in 120 to 200 minutes. A process of operating a repaired marine substrate in a water contacting environment with limited water absorption is also provided. A composition for use in these processes is also provided.
