Photoinitiator 2959

Photoinitiator 2959 may be used after adequate testing in UV

curable formulations on substrates like wood, metal, plastic and

paper. The hydroxy functional group enhances the compatibility of

2959 in water-borne coating formulations.2959 demonstrates low volatility and low odor as a pure substance as well as in cured films, compared to other commercially available photoinitiators.

A further important feature of  2959 is the potential toreact the hydroxy functional group to form a grafted photoinitiator onto a resin backbone, resulting in system with minimum extractability of the photoinitiator.

Due to its unique secondary properties  2959 is especially recommended when high temperatures and air circulation are required for water evaporation prior to UV curing of  the coating and for formulations where minimum residual odor is required, e.g. in printing onto food packaging.The amount of  2959 required for optimum

performance  should  be  determined  in  trials  covering  a  concentration range.
