Um die beste Kratz- und Marmorierfestigkeit zu erreichen, wurden verschiedene Beschichtungsarchitekturen f\u00fcr Grundierung, Basislack und Klarlack entwickelt. <a href=\"https:\/\/nanovea.com\/nano-scratch-tester\/\">Nanoscratch-Pr\u00fcfung<\/a> wurde als Standardtestmethode zur Messung der mechanischen Aspekte des Kratz-\/Marschverhaltens von Lackbeschichtungen entwickelt, wie in ASTM D7187 beschrieben<a href=\"#_edn1\" name=\"_ednref1\"><\/a>.
