PRODUCTS DESCRIPTION

					

						
CAS No.: [162881-26-7]  Bis(2,4,6-trimethylbenzoyl)-phenylphosphineoxide
Lotcure 819 is a versatile  photoinitiator for radical polymerization of unsaturated resins upon UV and near visible light exposure. With the below three advantages, has successfully solved the problems that often frustrate formulators: I. Good performance of curing pigmented formulations and in outdoor applications, it can be formulated with UV absorbers to gain good weather stability, while without harming the cure speed. II. Good through-curing of thick coating film. III. To give a clean white appearance in contrast to the off-white color
associated with other long wavelength absorption photoinitiators.
