Highly versatile, liquid photoinitiator that provides low yellowing and good surface cure when used at 0.5-5 wt% in UV curable formulations. 1173 shows similar reactivity to 184 and both are widely used in high quality coatings and varnishes. 1173 can be combined with other photoinitiators in thick films to overcome oxygen inhibition.
