LOTSORB UV 477 (CAS:)

Introduction

Lotsorb UV 477 is a liquid, high performance UV absorber developed for solvent borme and liquid UV curable coatings.

Based on a red shifted tris-resorcinol-triazine chromophore, it is suited for the protection of UVA range sensitive substrates or ingredients. Lotsorb UV 477 functions as a broad-spectrum UV absorber with high extinction particularly in the UVA range (320-390 nm) designed to block UVA light from sun and artificial lighting sources. Its high thermal stability and photopermanence makes it suitable for coatings exposed to high bake temperatures and/or to extreme environmental conditions. It fulfills the long term durability requirements of high performance decorative and industrial coatings.
