Matting Energy-Curable Coating Through Novel Dispersant Technology
Rebecca (Becca) Banton, Evonik Corporation
Abstract: Energy-curable coatings continue to grow and provide multiple benefits to the wood coatings industry. The ability to decrease gloss levels within the traditional 100% solids or solvent reduced systems has always been a challenge. With this in mind, novel dispersants are being developed to allow the formulator the ability to utilize common silica-based matting agents to achieve extremely low gloss levels. Not only is it possible to achieve low gloss levels, but these novel dispersants perform at a rheological profile which is commercially acceptable. In this study, novel dispersant technology is explored to provide formulation guidance on how to achieve low gloss or matte systems, while maintaining a workable viscosity using traditional matting agents.
