WebSolyfast 0010 can be photoactivated. The spectra shown in the graph above shows at what wavelength the photolatent catalyst absorb (and as a result triggered) by light. Solyfast 0010 is a colorless material, but it can absorb light strongly in the UV-B and UV-A spectral regions. Webphotolatent NHC would have distinctive advantages compared to a thermally latent analogue: release of free NHC at ambient temperature (considering that many NHC-mediated polymerizations can be conducted without heating), higher temporal resolution in the order of seconds, and spatial resolution opening novel applications such as …
