摘要
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.
