This article explores the use of NEAT additives for a UV-curable waterborne resin, which yields a photostable coating.
In recent years the field of waterborne UV-curable coatings has taken on greater significance as the coatings industry recognizes how it can help increase production efficiencies, lower volatile organic compounds (VOCs), and deliver high-end performance.(1,2) In previous papers, BASF described how various waterborne urethane acrylate dispersions could be photocured and also photostabilized.(3,4) We found a particularly effective strategy for photocuring was to use two or more photoinitiators.
