Micronized Montan Wax as Dispersing Aid for Powder Coatings
Spring 2002 Vol. 4, No. 1
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.
