Effect of Photo-Initiator on Curing Rate of Water-Base UV Varnish

Abstract:

The photo-initiator has a crucial role in the curing system of water-base UV varnish. The formulation of water-base UV varnish was designed and 4 different photo-initiators were chosen to make samples to study the effect of photo-initiator on the curing system of varnish. The curing results were tested and were compared. The results showed that the type and proportion of photo-initiator has great effects on the curing rate of water-base UV varnish, the best photo-initiator is 907. The mixed photo-initiators 907, TPO and ITX have been designed and the samples were prepared using the way of a formulation experiment. The result indicated that the curing rate of complex photo-initiator was lower than the curing rate of photo-initiator 907. The curing effect of the varnish samples is the best when the quantity of photo-initiator 907 is 6%。
