Utilizing Hyperbranched Structures in UV Curing Systems

To respond to an increasing demand for new high performance oligomers for UV formulations, new hyperbranched oligomer structures have been developed. They offer an interesting new look at UV curing chemistry. It will be shown in this paper that compared to traditional structures, hyperbranched materials offer lower viscosity at given molecular weight, high reactivity, and beneficial physical properties. Modifications to the basic structure also supply other advantages such as enhanced pigment wetting. These new oligomers can be advantageously used in UV formulations. The benefits of their introduction in applications such as UV inks, pigmented systems for industrial coatings, and other speciality applications will be presented.
