Overcoming the Effects of Oxygen on Cured and Uncured Uv Formulations

Molecular oxygen can be thought of as a diradical. Its singlet
state is unstable and quickly converts to the triplet which is
molecular oxygen's electronic ground state. This diradical lacks
the energy to initaiate polymerizations, and, therefore, is
considered stable. While notbeing able to initiate
polymerizations, it does readily react with already existing
radicals. Because of this nature, molecular oxygen plays an
important part in formulations that undergo a free radical
polymerization.
