Irgacure-651 Datasheet DC Chemicals
Description Irgacure 651 is a photoinitiator to enhance the polymer degradation. It was found that the addition of the Irgacure 651 to PMMA accelerated|the photooxidative degradation, particularly at the early stages of exposure. The efficiency of formation of chromophoric groups in PMMA in the presence of the Irgacure initiator was significantly greater than in pure polymer. This suggests that the free-radical products of the initiator photolysis (mainly benzoyl radicals) are able to abstract hydrogen atoms from PMMA molecules.
