Chemical/Physical Nature
DERAKANE 411-350 epoxy vinyl ester resin is based on bisphenol-A epoxy resin and has become the “industry standard” due to its wide range of end-use applications and ability to be used in a wide range of fabrication techniques. The raw materials used in the manufacture of this resin are listed as acceptable in FDA regulation Title 21 CFR 177.2420 for repeated use in contact with food, subject to user’s compliance with the prescribed limitations of that regulation.
Equipment fabricated with DERAKANE 411-350 resin has superior elongation and toughness and better impact resistance and less cracking due to cyclic temperature, pressure flutuations and mechanical shocks providing a safety factor against damage during process upsets or during shipping installation. Composites fabricated with DERAKANE 411-350 resin provide resistance to a wide range of acids, alkalis, bleaches and solvents. This resin holds up well in corrosive invironments, postponing the need for replacements. Equipment fabricated with DERAKANE 411-350 resin tolerates heavy design loads without causing failure due to resin damage. This facilitates working with large weight-bearing equipment with confidence.
Applications and Use
DERAKANE 411-350 resin is designed for use in fabricating FRP storage tanks, vessels, ducts and on-site maintenance projects, paticularly in chemical processing and pulp and paper operations.
– The resin is designed for ease of fabrication using hand lay-up, spray-up, filament winding, compression molding and resin transfer molding techniques, pultrusion and molded grating applications.
– An alternate viscosity, optimized for some vacuum infusion processes is available as DERAKANE MOMENTUM 411-200 resin.
– An alternate for low styrene content (HAP) is available as DERAKANE 441-400 resin.
