Finally, the corrosion barrier is backed with a epoxy vinyl ester resins (from this point forward referred to as structural laminate that provides the strength and stiffness Derakane™ resins) are designed and manufactured by INEOS. for the overall FRP structure. This guide provides guidelines Derakane™ resins possess outstanding corrosion-resistant for selecting the most appropriate resin for the corrosion- and temperature-resistant properties, which make them well- resistant equipment in question. Recommendations in this suited for a variety of demanding industrial applications. With guide apply to a variety of corrosion-resistant structures. performance that has been proven over more than 50 years, Because many variables that affect the performance of a Derakane™ resins not only deliver durable solutions, they also laminate are beyond INEOS’ control, no warranty concerning provide a high measure of confidence. the use of Derakane™ epoxy vinyl ester resins can be made. This guide briefly describes the various Derakane™ resins, as The temperatures shown in this guide are supported by well as detailed chemical resistance data needed to assist extensive corrosion testing and/or case histories. When engineers in specifying and designing corrosion-resistant these guidelines are followed, properly designed, fabricated fiber reinforced polymer (FRP) applications. and installed equipment made with Derakane™ resins should provide excellent service life. FRP materials are designed with a corrosive-resistant barrier to enhance performance and longevity. Their For the design of FRP equipment, prospective users of corrosion-resistant properties make FRPs an ideal structure Derakane™ resins should refer to the appropriate industry for tanks, pipes and ducts in environments where corrosive standards and design guidelines. materials are present. These structures are typically For more information, contact INEOS Technical Service at designed with a corrosion barrier that serves to minimize [email protected] or by visiting www.derakane.com. penetration of a corrosive media into the structural portion of the equipment. Typically, the entire corrosion barrier is 2.5 to 6.3 mm (100 to 250 mil) thick. The first layer of the corrosion barrier is usually 0.3 to 0.8 mm (10 to 20 mil) 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 4 BRIEF PRODUCT DESCRIPTION Derakane™ 411 series resins are the globally recognized Derakane™ 455-400 resin is an unpromoted, highly Derakane™ 510N resin is a brominated epoxy novolac standard for epoxy vinyl ester resins. They are based on crosslinked novolac epoxy vinyl ester.

It offers exceptional hot vinyl ester resins that offer a high degree of fire retardance.1 epoxy vinyl ester resin that offers very high toughness, impact water, solvent and acid resistance, excellent impact strength The incorporation of bromine not only provides flame and fatigue resistance and excellent adhesion. It is the resin of with high heat resistance and tensile elongation. retardancy, but also contributes to better toughness and choice for demanding structural applications and as a primer fatigue resistance when compared to standard epoxy vinyl for chemically resistant FRP linings. ester resins. Derakane 510™ resins are also very resistant to chemical attack in chlorine and bleach environments. 1 The degree of retardance achieved in properly formulated cured products made of these resins is most frequently quantified by the ASTM E84 tunnel test. This is a controlled test that compares flammability characteristics of one material with another, but may not be predictive of behavior in a real fire situation. Derakane™ and Derakane™ Momentum™ epoxy vinyl ester resins are organic materials and will burn under the right conditions of heat and oxygen supply. 5 HOW TO USE THE CHEMICAL RESISTANCE TABLE CONTENT This listing of chemical reagents and environments shows Each series of Derakane™ resins is based on the same In the chemical resistance tables, a blank space indicates the highest known temperature at which equipment made epoxy (or novolac) vinyl ester resin backbone.
