Abstract
Disclosed are wheelsets having a cured coating produced from the application and curing of a composition comprising a component A comprising a1) 18 to 30% by weight of a polyether polyol with a hydroxy number of 300 to 500 mg KOH/g, a2) 38 to 60% by weight of castor oil, a3) 0.6 to 2.0% by weight of at least one di- or polyamine, a4) 5.6 to 9.0% by weight of trizinc bis(orthophosphate), a5) 2.2 to 3.5% by weight of zinc oxide and/or zinc phosphate, a6) 0.05 to 0.4% by weight of a catalyst which catalyzes urethane formation, where the percentage by weight data are based on the total mass of the coating composition, and a component B comprising one or more di- and/or polyisocyanates in an amount corresponding to a molar ratio of 0.6:1 to 1.2:1 of the isocyanate groups to the hydroxy groups of the constituents a1) and a2).
