Abstract
The present invention relates to a method for producing matt and scratch-resistant coatings that takes place under exposure to actinic radiation on coating systems containing activated double bonds under radical polymerisation.
Claims11
A method for producing matt surfaces comprising:
- (1) applying a radiation-curable coating agent to a substrate;
- (2) irradiating the radiation-curable coating from step (1) with UV light having a wavelength from ≧200 nm to ≦420 nm in a radiation dose from 25 to 120 mJ/cm2,
- (3) irradiating the coating obtained from step (2) with UV light having a wavelength from ≧120 nm to ≦230 nm,
- (4) finish-curing the coating obtainable from step (3) by actinic radiation.
