DERAKANE® 441-400 epoxy vinyl ester resin is a lower styrene-content resin that has an optimized epoxy backbone and resulting superior thermal properties and corrosion resistance performance which place it as a resin type between DERAKANE 411-350 and DERAKANE 470-300 resins. DERAKANE 441-400 resin offers superior stability compared to conventional vinyl ester resins which provide additional flexibility to fabricators in storage and handling.

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, subjerct to user's compliance with the prescribed limitations of that regulation.

APPLICATIONS AND USE
DERAKANE® 441-400 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. This resin is recommended for fabricationg FRP storage tanks, vessels, ducts, and on-site maintenance projects, particularly in chemical processing, pulp and paper operations, including chlorine dioxide bleaching towers.
