Process for producing scratch resistant coatings and its use, in particular for producing multilayered coats of enamel

摘要

The present invention relates to a process for producing scratch-resistant coatings which comprises applying a coating composition which in the cured state has a storage modulus E' in the rubber-elastic range of at least 107.6 Pa and a loss factor tan delta at 20° C. of not more than 0.10, the storage modulus E'0 and the loss factor having been measured by dynamic mechanical thermoanalysis on homogeneous free films having a film thickness of 40±10 mum. The present invention additionally relates to the use of the process for producing multicoat finishes and also to coating compositions suitable for this process.
