Blend of 2-4-6 trimethylbenzophenone and 4-methylbenzophenone
PowerCure™ 503 is particularly indicated for the photo polymerisation of UV curable systems when highreactivity, low curing odour and low yellowing are required. The radical generation occurs via hydrogen abstraction by the action of a co-initiator such as tertiary amines.
