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.

Abstract: An Additive Package is provided to adjust the cure properties of a two-part bonding filler across a temperature range of from 4 and 44 degrees Celsius. A low temperature additive speeds a cure rate between 4 and 15 degrees Celsius and a high temperature additive slows down a cure rate between 25 and 44 degrees Celsius. The amount of Additive Package is varied to account for the desired cure properties. The Additive Package includes a first unsaturated polyester resins with an average degree of unsaturation of 70-100 percent based on total acid and anhydride monomer content. A process for repairing a vehicle body is provided using the Additive Package. A kit for accomplishing repairs in an after-market repair setting is also provided.

Abstract: A free radical curable automotive body primer is provided that has a color change corresponding to the progress of the cure process until a dry to sand condition has been attained and an internal colored guide coat that does not change color given its exposure to ambient air and as a result, has a different color on the surface of the primer than when in bulk, allowing for the detection and removal of low spots or other imperfections from a vehicle body by additional sanding of the inventive primer to remove oxidized guide coat colorant surface regions. The cure color change is achieved through resort to at least one color changing dye that reacts with a free radical cure initiator during the vehicle body priming process and changes color to indicate when the primer composition has achieved a level of cure so as to be dry enough to sand.
