DERAKANE 411-350 WSR Series epoxy vinyl ester resins are based on bisphenol-A epoxy resin.DERAKANE 411 Series epoxy vinyl ester resins have become the "industry standard" due to their widerange of end-use applications and ability to be used in a wide range of fabrication techniques. The rawmaterials used in the manufacture of these resins are listed as acceptable in FDA regulation Title 21 CFR177.2420 for repeated use in contact with food, subject to user's compliance with the prescribedlimitations of that regulation. DERAKANE 411-350 WSR and WSR-20 resins are recognized registeredcomponents in a coating system Certified by NSF(1) to ANSI/NSF Standard 61, Drinking Water SystemComponents. DERAKANE 411-350 WSR resin may be cured using cobalt/MEKP or BPO/DMA wherecobalt free systems are required - e.g. bleach service within the limits prescribed by Ashland's technicalservice team.
Equipment fabricated with DERAKANE 411-350 WSR Series resins exhibit superior elongation,toughness and impact resistance. This physical resilience offers greater resistance to cracking due tothermal cycling, pressure fluctuations and mechanical shocks providing a safety factor against damageduring process upsets or during shipping and installation. Composites fabricated with DERAKANE411-350 WSR Series resins provide resistance to a wide range of acids, alkalis, bleaches and solvents.These resins hold up well in corrosive environments, postponing the need for replacements. Equipmentfabricated with DERAKANE 411-350 WSR Series resins tolerate heavy design loads without causingfailure due to resin damage. This facilitates working with large weight-bearing equipment with confidence.
