Functional Additives for Energy-Curable Coatings

Christopher M. Howard, Wernfried Heilen, Susanne Struck, Troy Moss

Abstract


Today’s regulations demand lower solvent emissions to minimize the Volatile Organic Compounds (VOCs) and environmental impact caused by the manufacture, application, and cure of coatings. In an effort to accomplish this objective, a number of methods have been deemed appropriate. One of these approaches involves an energy-curable coating system that is centered on functional or crosslinkable chemistry. This paper will present an overview of research on the chemical modifications designed to overcome the technical limitations of additives for these coating systems such as surface control, entrained air, and substrate wetting. In particular, the research explores the use of organo-modified polysiloxanes, as well as their influence on energy-curable coatings.
