(a) Polymerization profiles of EPOX (epoxy function conversion vs. irradiation time) upon exposure to the LED@405 nm under air in the presence of different photoinitiating systems: (1) Cd7/Iod (0.5%/1% w/w); (2) Cd1/Iod (0.5%/1% w/w); (3) Cd3/Iod (0.5%/1% w/w); (4) Cd2/Iod (0.5%/1% w/w); (5) Cd4/Iod (0.5%/1% w/w); (6) Cd5/Iod (0.5%/1% w/w); (7) Cd6/Iod (0.5%/1% w/w); (8) BAPO/Iod (0.5%/1% w/w); (9) CARET/Iod (1%/1% w/w); IR spectra recorded before and after polymerization using: (b) Cd7/Iod (0.5%/1% w/w); (c) CARET/Iod (1%/1% w/w). The irradiation starts at t = 10 s.
