RESIN SELECTION GUIDE FOR CHEMICAL RESISTANCE DERAKANE ™ RESINS FOR CORROSION-RESISTANT FRP APPLICATIONS

DERAKANE CHEMICAL RESISTANCE GUIDE ™ FOREWORD Derakane™, Derakane™ Momentum™ and Derakane™ Signia™ epoxy vinyl ester resins (from this point forward referred to as Derakane™ resins) are designed and manufactured by INEOS. Derakane™ resins possess outstanding corrosion-resistant and temperature-resistant properties, which make them wellsuited for a variety of demanding industrial applications. With performance that has been proven over more than 50 years, Derakane™ resins not only deliver durable solutions, they also provide a high measure of confidence. This guide briefly describes the various...

BRIEF PRODUCT DESCRIPTION Derakane™ 411 series resins are the globally recognized standard for epoxy vinyl ester resins. They are based on bisphenol-A epoxy resin, providing resistance to a wide range of acids, alkalis, bleaches and solvents for use in many chemical processing applications. They offer excellent toughness and fatigue resistance. Derakane™ 441-400 resins are low styrene monomer bisphenol-A epoxy vinyl ester resins with mechanical, thermal and chemical resistance properties between Derakane™ 411 and Derakane™ 470 resins. Their unique combination of high HDT and elongation makes...

HOW TO USE THE CHEMICAL RESISTANCE TABLE CONTENT Each series of Derakane™ resins is based on the same epoxy (or novolac) vinyl ester resin backbone. Improvements have been made over the years for processing and stability, as seen in our recent introduction of the Derakane™ Signia™ resins. For example, Derakane™ 411-350, Derakane™ Momentum™ 411-350 and Derakane™ Signia™ 411-350 resins each are based on the same polymer backbone, and comparison studies confirm that their performance in corrosive environments is essentially equivalent. Corrosion data and case history information for each series...

FOOTNOTES Information indicated in footnotes is essential in order to ensure a good service life of FRP equipment. It is strongly recommended that they are followed. 1 Double synthetic veil should be used in the CR barrier. Carbon veil can be used in alkaline environments above 50 °C/120 °F and in hydrofluoric acid environments for maximum corrosion resistance. 2 Post cure recommended to maximize service life. 3 Benzoyl Peroxide/Amine cure system recommended to increase service life. 4 Recommended, provided the recommended resin is also suitable for the solvent used for dissolution. 5 Satisfactory...

POST CURE For a service temperature below 100 °C/210 °F: A post cure may extend the service life if the operating temperature is within 20 °C/40 °F of the present CR guide maximum temperature for the service. This means that a post cure can be beneficial for solvent applications with a temperature limit of 25–40 °C/80–100 °F. For a service temperature above 100 °C/210 °F: Post cure in service may be sufficient, provided the resinspecific minimum Barcol hardness values are reached before startup. VEILS For service in pure and neutral salt solutions: Post cure may, in general, not be required,...

SPECIAL CASES INSUFFICIENT INFORMATION HIGH (FLUE) GAS TEMPERATURES In cases where the environment or exposure conditions are outside the scope of this guide, and thus no specific recommendations can be made, a test laminate should be exposed to the actual or simulated conditions proposed so that a final decision on resin suitability can be reached. If a synthetic veil is recommended for hot gas environments, the temperature resistance of the veil must be sufficient. COATINGS AND LININGS (REINFORCED AND NON-REINFORCED) Coatings and linings have their own specific properties and may be limited...

MIXTURES OF ALTERNATING ENVIRONMENTS CHEMICAL RESISTANCE INQUIRY The information provided in this guide represents the performance of full FRP structures under continuous use in contact with the stated chemical environment (unless otherwise indicated). It is sometimes difficult to predict just how aggressive certain combinations of chemicals will be toward FRP. Some mixtures are more aggressive toward FRP than the individual components, so special attention should be paid to aggressively synergistic chemicals which cannot readily be predicted based solely on the corrosion properties of the individual...
