| Résumé : |
Various photoinitiators were tested in simple clearcoat formulations based on two aqueous UV curable resin emulsions (both unsaturated polyester and polyester acrylate) and on two polyurethane acrylate dispersions. Predrying temperatures, initiator concentrations, and incorporation methods were varied. Pendulum hardness on glass allowed a rapid estimation of the curing results. Crystalline 2-hydroxy-2-methyl-1-[4-(2-hydroxyethoxy)-phenyl] propan-1-one (no. 3 of the initiator types investigated) gave superior curing response especially at lower photoinitiator levels which could be easily incorporated. On the other hand, other photoinitiator types were useful in significantly higher concentrations, too. Thus, they also made possible similar results. |
