APPLICATION
U 210 Monuron accelerator similar as UR200 ,well combined with DICY by reducing the time and required temperature of epoxy curing:
★ structural adhesives e.g. conductive resin
★ Powder coatings
★ Prepregs of epoxy composites
★ Encapsulation compounds for electronic industry
★ Reinforcements e.g. carbon fiber
ADVANTAGES
U 210 Monuron with a similar function with UR200 brings a moderate curing speed . the outstanding achievement is showing a longer latency -shelf life can be up to min. 5 months for finished systems than other UR accelerators.
U 210 Monuron is suggested to be added at the percent < 5 phr Curing can be finalized within 70 minutes at 100°C and less than 20 minutes at 140°C.
