Abstract: A process for repairing a marine surface is provided that includes the mixing of the part A and the part B until a terminal color change occurs within ±5 minutes of cure. The mixture is applied to a substrate of the marine surface in need of repair to a thickness of up to 6.35 mm. The cured mass has water absorption less than of 0.2% in freshwater or 0.15% in ocean water salinity. A marine repair composition is provided that includes in a part A: an unsaturated vinyl ester resin, a reactive diluent, a cure promoter, a cure inhibitor, a corrosion inhibitor and a filler. The part B includes a free-radical cure initiator stored separately from the part A until mixed with the part A to form the composition.

Abstract: A method for repairing a defect in a vehicle exterior body surface is provided that includes a scan data set being generated that corresponds to the dimensional surface boundaries of the defect. A manufacturing data set is created for an object at least in part complementary to the defect from the scan data. The object is formed from the manufacturing data set with a layered manufacturing device. The object is joined to the defect to repair the vehicle exterior body surface. An object is also provided formed of a thermoplastic or a UV cured polymer with a shape that is at least at least in part complementary to a defect vehicle exterior body surface. The object having a void therein with the shape configured to receive an insert or a fastener therein.

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.

Abstract: A free radical cure catalyst composition is provided that includes a free radical cure catalyst present as a paste at 20° C. A cure inhibitor is dissolved in a solvent compatible with the free radical cure catalyst paste to form an inhibitor solution that is mixed into the paste. A filler composition is also provided that includes an ethylenically unsaturated resin, a crosslinking agent; and the free radical cure catalyst composition. A method of repairing a vehicle body is provided that includes an uncured layer of the composition as noted above is applied to a substrate. The uncured layer is modified during a working time of from 8 to 35 minutes. The uncured layer is allowed to cure under free radical conditions to form a cured layer.

Abstract: A bond fill composition is provided that includes a part A including a curable resin having a degree of unsaturation, an inorganic hydrate filler present in an amount to confer fire suppression time of 60 seconds or less upon cure, and a monomer reactive diluent in which the curable resin is dissolved or suspended. A part B storage-separate, free-radical cure initiator package is provided that includes a free-radical cure initiator. 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.
