Abstract
Styrene-free unsaturated polyester resin and vinyl ester resin compositions are provided which contain low amounts of hazardous air pollutants, good mechanical and physical properties, and good corrosion resistant characteristics. The resin systems are such that minimal or no component is leachable after completion of the curing process. The resins are suitable for repair of sewer pipes and potable water pipe systems as part of a cured-in-place pipe application. Additionally, the invention is suitable for relining of storage tanks. A process for the manufacture of these resin compositions is also provided.
