Since its introduction to market, this photoinitiator has rapidly gained its popularity in the application of UV ink and solder mask. Doublecure® 107, when irradiating with UV light, undergoes a homolytic and intramolecular type of breakage to generate a pair of free radicals to initiate the polymerization of UV curable systems. This white crystalline powder is strongly recommended for the pigmented UV system due to its strong absorbance (ε= 18,600 at 305 nm) in the wavelength region usually blocked by the commonly used pigments, such as TiO2 and phthalocyanine. Doublecure® 107 will not cause yellowing problems under normal conditions. view less | |
