Description

Lencolo 5020 Exhibits stronger absorption in both the UV and visible light regions and is more effective than other photoinitiators in initiating curing in pigmented coating systems. It shows minimal yellowing after curing and under prolonged light exposure, making it suitable for applications with strict yellowing requirements, such as white or light-colored inks and coatings. Additionally, it has photobleaching properties, allowing light to penetrate the coating and promoting thorough curing of thick films.
