Vicura mc-31

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.

Vicura MC55 (Pyrromelletic Acid Diphenyl Imidazoline Salt 12) is an offwhite powder with the following chemical formula C10H6O8.2C9H10N2 The curing mechanism between Vicura MC55 (Pyrromelletic Acid Diphenyl Imidazoline Salt 12) 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 MC 55.

Vicura MC2844 (1otolylbiguanide) is an offwhite powder which has C9H13N5 as chemical formula. This substance finds its application in powder coatings and is also known as substituted dicyandiamide or modified dicyandiamide. nter content here. Availability Europe Vicura MC2844 is on stock in our local warehouses. Our leadtime is about one week if delivered in 25 KG carton boxes. Canada, South America, South Africa and other markets can also be served, please contact our sales department for more details.

A micronized grade of dicyandiamide containing 1.5%1.6% antiblocking agent to inhibit clumping and improve handling. It is used as curing agent for epoxy resins. Due to its high melting point Vicura DICY 100S does not melt during extrusion to produce a homogeneous mixture with the epoxy resin on a molecular scale. Therefore Vicura DICY 100S is supplied with low particle size assuring in this way acceptable homogeneity during the extrusion step, provided the premixing process is done properly. Outstanding features of epoxy powder coatings cured with Vicura DICY100S include excellent adhesion to metal, excellent chemical and solvent resistance, very high impact, abrasion and scratchy resistance, and dielectric properties that make them suitable for many electrical applications. Availability Europe and United States Provided Vicuta DICY 100S is on stock in our local warehouses our lead time is about one week if delivered in 20 KG carton boxes.
