2 Hetron Resin Selection Guide English Foreward Hetron and Derakane epoxy vinyl ester resins are designed and manufactured by Ashland. These resins possess outstanding corrosion-resistant properties and satisfy critical requirements in Fiber- Reinforced Plastic (FRP). Because of their outstanding corrosion-resistant properties, Hetron and Derakane resins are particularly well suited for demanding industrial applications. This latest edition of the Hetron Resin Selection Guide describes the various Hetron resins, and presents detailed chemical resistance data engineers need for specifying and designing corrosion-resistant FRP applications. It has been simplified and CAS numbers have been added to make it more userfriendly. Several products including Hetron 970/35, Hetron 942/35, Hetron 92 and Hetron 99P have been removed as well as all Aropol Polyester resins. For information on any of these products, please contact Ashland Technical Service at hetron@ashland.com. Recommendations provided in this guide apply to “state-of-the-art” corrosion-resistant structures. Typically these structures have a corrosion barrier that is 2.5 to 6.3 mm (100 to 250 mils) thick and are designed for contact with a specific chemical environment. The first layer of the corrosion barrier usually is 0.3 to 0.8 mm (10 to 20 mils) thick and is 95% resin, reinforced by one or two surfacing veils. This layer is then backed with 2 to 6 mm (90 to 230 mils) of 75% resin, reinforced with chopped strand mat (powder binder only). Finally, the corrosion barrier is backed with a structural laminate that provides the strength and stiffness for the overall corrosion-resistant composite structure. Because many of the variables that affect the performance of a laminate are beyond Ashland’s control, no warranty concerning the use of Hetron epoxy vinyl ester resins can be made. Recommendations herein are based on a variety of sources, including evaluations of actual field service performance, laboratory (ASTM C581) and field tests of FRP laminate construction, and the combined knowledge of an experienced staff. The service conditions shown in this bulletin are believed to be well within the capabilities of Hetron epoxy vinyl ester resins when laminates are properly designed, fabricated, and installed. For the design of FRP equipment, prospective users of Hetron resins should refer to the appropriate industry standards and design guidelines.
