Abstract: A series of polyester and vinyl ester based insoluble binder compositions for use with fiberglass are provided. These compositions are comprised of cross-linkable unsaturated resins used in tandem with various azo initiators. The compositions are capable of thermally curing; creating a water and organic-insoluble binder exhibiting good adhesion to glass. These thermally cured binders are able to provide similar fiberglass tensile strength to the conventional dibenzoyl peroxide containing compositions, while exhibiting improved retention of whiteness over time.

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.
