Abstract
The present invention relates to a process for the preparation of coatings by reacting polyurethane single component systems, which preferably contain at least one prepolymer containing NCO groups in bonded form and a latent hardener, whereby the polyurethane single component system is mixed with steam at a temperature from 100.degree. C. to 500.degree. C., and fed under a pressure of 0.5 to 10 bars, and finally sprayed using a general spray method. The coatings so formed cure bubble free independent of the moisture content of the surroundings and without exhibiting coating mass runoff.
