It is important to know UV curable coatings especially in dry faster system. Light stabilizers including UV absorber (UVA) and hinder amine light stabilizers (HALS) are known to prevent coating damages caused by UV irradiation.

Photo initiator absorbs UV energy to initiate curing processes. UV absorber absorbs UV energy to prevent coatings damages. As a result, UV absorber and photo initiator are competing for UV energy to cause negative impacts about cure speed.
