Montan Waxes are vegetable fossil waxes that are derived from wax-rich lignite and peat. These original raw materials have to be extracted, de-resinified and oxidized. The resulting product is a so-called Montan Wax Acid, a pale yellow wax that can be, among other things, esterified. Basically, Montan waxes consist of a carbon chain length between 24 and 32 and have acid values between 15 and 140 mg KOH/g.
One of these Montan waxes is Ceridust 5551, a micronized ester wax with an acid value of 15 mg KOH/g and an average particle size diameter of 8.5 µm. The drop point, or melting point range, is between 95°C and 101ºC.
The preceeding graphs show the effect of several wax concentrations on pigment dispersion and extruder throughput rates for a hybrid powder coating.
