Ein hoher Wert der Pendelhärte steht für eine hohe Härte des resultierenden Lackfilmes. Die Proben mit Glycerinmonomethacrylat weisen eine wesentlich verbesserte Medienbeständigkeit gegenüber dem Polymerfilm auf, der kein GMMA enthält. Das molare Verhältnis von GMMA/HEMA=1/1 zeigt die besten Eigenschaften.
A high value of the pendulum hardness stands for a high hardness of the resulting paint film. The glycerol monomethacrylate samples have significantly improved media resistance to the polymer film which does not contain GMMA. The molar ratio of GMMA / HEMA = 1/1 shows the best properties.
