Epoxy Vinyl Ester Resin for fabrication efficiency and product quality improvement
DERAKANE MOMENTUM 411-350 epoxy vinyl ester resin is based on bisphenol-A epoxy resin and provides resistance to a wide range of acids, alkalis, bleaches, and organic compounds for use in many chemical processing industry applications. These resins are a new generation of resins that can be used to improve fabrication efficiency and product quality.
Their lighter color makes defects easier to see and correct while the resin is still workable. The resin’s improved reactivity properties often permit an increase in the lay-up thickness per session. The longer stability provides additional flexibility to fabricators in storage and handling.
• Holds up in corrosive environments, postponing the need for equipment replacement
• Tolerates heavy design loads without causing failure due to resin damage therefore can work with large weight-bearing equipment with confidence
• Superior elongation and toughness provides FRP equipment with better impact resistance and less cracking due to cyclic temperature, pressure fluctuations, and mechanical shocks providing a safety factor against damage during process upsets or during shipping installation
• When properly formulated and cured, complies with FDA regulation 21 CFR 177.2420, covering materials intended for repeated use in contact with food.

The following tables provide typical
(1) geltimes for methylethylketone peroxide (MEKP).The MEKP Cure System Typical geltimes(2) using NOROX(3) MEKP-925H(4) catalyst (MEKP) and Cobalt Naphthenate-6%(5) (Co-nap6%), Diethylaniline (DEA) and 2,4-Pentanedione (2,4-P).
(2) Thoroughly test any other materials in your applications before full-scale use. Geltimes may vary due to the reactive nature of these materials. Always test a small quantity before formulating large quantities.

(4) Norox MEKP-925H or equivalent low hydrogen peroxide content MEKP. Use of other MEKP catalysts or additives may result in different gel times.
(5) Use of cobalt octoate, especially in combination with 2,4-P can result in 20-30% slower gel times.
(6) phr = parts per hundred resin molding compound
