Application
The higher solubility in epoxy resins compared to substituted dicyandiamide provides high- gloss clear coatings with high transparency and very good mechanical properties. In a high-gloss epoxy system Vicura MC-2844 (1-o-tolylbiguanide) gives good flow properties with best corrosion resistance at low curing temperatures.

  • Good miscibility with epoxy resins
  • Well levelling and outstanding mechanical performance
  • Excellent colour stability
  • Recommend using quantity of Vicura MC-2284 is 4~5% of the amount of epoxy resin
  • Realize hardening of 150 ͦC min or 180 ͦC min.
  • Used for epoxy powder coatings.
