CoREZYN® isophthalic resins are suitable for a wide range of conventional FRP/GRP applications. They are premium-grade, high-molecular weight, thermosetting resins formulated specifically for their physical and corrosion resistance properties.

For optimum performance and corrosion resistance, Interplastic uses the more exacting and expensive two-stage reaction for manufacturing its isophthalic resins. This process yields the best possible average molecular weight and molecular-weight distribution. In addition, the carefully designed mole ratios in these resins offer a significant improvement over conventional industry standards. CoREZYN isophthalic resins deliver superior performance, resulting from an optimum balance of reaction technique, esterification to a high molecular weight, and mole ratio of unsaturated acid to aromatic acid.

All of these resins have the same isophthalic "backbone" that gives them their corrosion resistant properties. Variations in the individual resin formulations result in a range of properties that provide different functional characteristics. This permits a great deal of versatility in finished-product formulation, while maintaining high corrosion resistance and physical properties.
