Abstract

The importance of an inline determination of the UV-curing degree during production increases. Practical offline techniques like i.e. the acetone rub test are in use to ensure a sufficient production process. The scientific crosslink between these test results and the actual polymerization degree is hardly given. This study shows a validated crosslink between established laboratory NIR analysis and UV-VIS readings. In conclusion it is shown that for practical application all necessary data can be acquired with industrial inline VIS spectral photometers.
