Analysis of Commercial Unsaturated Polyester Repair Resins

Abstract

The basic rheological, thermal, and mechanical properties of commercially available repair putties have been determined in this study, as has the composition of these products. These products contain 33% to 40% unsaturated polyester resin, 10% to 20% styrene, and 45% to 57% inorganic fillers. The fillers are made up of hollow glass microspheres, talc, magnesium carbonate, calcium carbonate, fumed silica, glass fibers, and various other minerals. These products have a glass transition temperature of roughly 25-deg C and a room temperature storage modulus of 2 to 4.6 GPa. These putties display shear thinning behavior as a result of the fillers. All of these properties provide important benchmark characteristics that must be more or less met by U.S. Army Research Laboratory/Drexel-invented environmentally friendly, hazardous air pollutant?free repair resins utilizing renewable fatty acid-based monomers.
