The curing mechanism between Vicura MC68 (Pyromellitic Acid Diphenyl Imidazoline Salt) and the epoxy resin is complex. Two parallel processes are taking place; direct reaction between the imidazoline and the epoxy group and homopolymerization of the epoxy resin that is catalyzed by Vicura MC68. Compared to most of the powder coating systems where the optimal ratio between the crosslinker and the binder is close to the stoichiometric one, in the case of Vicura MC68 the optimal ratio is generally determined empirically. For epoxy resins that are typically used for powder coatings (epoxy equivalent weights between 700 – 1000) amounts of 8,0 – 10,0 % of Vicura MC68 are recommended as good starting points. Also available with added calcium carbonate (Vicura MC68L) Availability Europe Vicura MC68 is on stock in our local warehouses. Our lead time is about one week if delivered in 20 KG carton boxes.
