Powertrain & Underhood

Arotran™ and Derakane™ resins can be used in the extreme environments that exist in powertrain and underhood applications without compromise to physical or mechanical properties. Arotran epoxy vinyl ester and unsaturated polyester resins provide the durability and superior heat resistance needed in these demanding applications while the Derakane epoxy vinyl ester resins have been providing unmatched reliability and trust to customers for 50 years.

Epoxy Vinyl Ester Resins


Derakane 788/780/782 Resin System

  • Derakane 788 resin system is a blend of thickenable bis-A epoxy vinyl ester resin and a low profile additive. This system is designed for use in SMC and BMC. Features include good heat resistance, excellent shrink control, high tensile elongation, and good dimensional tolerance.
  • Derakane 780 resin system is a thickenable novolac based epoxy vinyl ester resin for use in SMC and BMC applications. Derakane 780 resin system features include excellent physical properties, high heat and corrosion resistance, and good retention of physical properties up to 150 °C.
  • Derakane 782 resin system is a high-strength, thickenable, bis-A based epoxy vinyl ester resin for use in SMC and BMC. Features include excellent physical properties, good heat resistance, high tensile elongation, and good dimensional tolerance.
