Enhanced waterborne coatings through increased understanding of stratification mechanisms & control of particle distributions

Several desired properties of paints and coatings are believed to be closely linked to the distribution of the different coating components, e.g. latex particles, pigments or colloidal silica, in the coating layer. This project will build the necessary fundamental understanding of how parameters like rheology, drying and particle properties govern the movement of the coating components in the paint layer during the time from application to a dry paint film and their final distribution in the coating. Indeed, studies of the movement of components in full paint formulations are challenging. The research will therefore necessarily start with simple systems
(only 2-3 components) and complexity will then gradually be added to the system.
