CoREZYN® Isophthalic Corrosion Resistant Resins Technical Expertise and Superior Manufacturing Lead to Optimal Performance of Isophthalics.

Interplastic Corporation is the high-performance resin specialist you can count on. Since 1959, we’ve been working with manufacturers of reinforced plastic composites to build better, stronger, tougher and longer-lasting products.

Our technical resin specialists are problem solvers. We can define specifications to conform to your production and end use requirements and then formulate a resin to meet those needs. We can consult with you on structural or composite questions and accurately test resin or finished product samples in our laboratories. General Product Background

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. Laminating Resins All of the CoREZYN isophthalic corrosion resistant resins are available in promoted or non-promoted and thixotropic or non-thixotropic formulations.

These resins are used most often in a promoted, thixotropic form designed for an ambient condition cure to yield high-strength corrosion resistant laminates. The thixotropic properties and the additives used provide superior viscosity stability. Furthermore, the additives and the chemistry work together to maintain optimum handling characteristics such as consistently superior glass wet-out, high physical properties and excellent corrosion resistance. The product number prefix “75” describes the base resin formulation. The most commonly used resins in this group are: COR75-AQ-001, COR75-AQ-010, COR75-AQ-066 and COR75-AQ-393. COR75-AA-011 series is UL 1746-approved. COR75-AQ-460 is UL 1746 and UL 1316-approved.

For manufacturers who prefer a non-promoted version, promoter/catalyst tables are available from Interplastic’s Thermoset Resins Division laboratories for a methyl ethyl ketone peroxide (MEKP) or a benzyl peroxide (BPO) curing system. Filament Winding Resins CoREZYN isophthalic filament winding resins include formulations for ambient- or high- temperature cure, with or without thixotropic properties for filament winding applications. The product number prefix “26” describes this series. Many of the filament winding resins we supply are tailor-made formulations. Pultrusion Resins CoREZYN isophthalic pultrusion resins are used in diverse applications such as nuclear power plant cooling tower grids, fence stock, tubes and structural shapes, fuse bodies, walkway grids and window lineals. Formulated with a wide range of catalyst and physical capabilities, these pultrusion resins are designated with a prefix of “30”. Interplastic also has fire retardant and/or vinyl ester polymers available for pultrusion applications. Isophthalic Chemical Resistance Effective chemical resistance is determined by several criteria. The principal test procedure is ASTM C581 with a minimum exposure time of one year. The temperature and/or concentration limits shown in the tables that follow do not necessarily constitute the limits to which the laminate can be safely used; they may only represent the limits to which testing has been performed. For exposures different from these limits, we recommend using our searchable data base: www.resinwizard.com. If you need additional assistance, contact Interplastic’s Thermoset Resins Division laboratory at [email protected]. Cured-In-Place Pipe (CIPP) Resins CoREZYN isophthalic resins are extensively used in CIPP applications and provide a cost- effective alternative to vinyl esters when those high-performance resins are not required.

CoREZYN isophthalics are promoted to provide predictable stability that meets your requirements whether you are impregnating the liner at the factory or at the job site. Resins can be modified for ambient- or high-temperature cure depending upon your needs.
