Different photoinitiator systems covering the emission profile of the sun were investigated in a radical crosslinking system. Different acrylates selected from polyols, urethanes and epoxyacrylates were used in the studies to obtain a rough image regarding conversion and crosslinking efficiency. The systems were screened by different methods; that is FTIR, photo-DSC, and sol-gel analysis. Experiments were carried out under different solar radiation intensities and compared with experiments obtained using artificial light sources (LEDs, Xe lamp).
