Grant: Collaborative Research and Development Grants

In order to establish the parameters for the optimal design and development of RDTP, fundamental understanding on the fast dry mechanism is needed. We will develop analytical tools for the quantification of drying rates for paint formulations based on spectroscopic technique. By careful analyses of the structural-property relationship between the components of RDTP, critical factors that control this process will be identified. Based on this knowledge, we will develop protocols for the manufacture of suitable polymer colloids and additives that are critical for the formulation of RDTP. Additional improvements to the RDTP, such as better drying behaviour, improved adhesion to road surface, enhanced wear properties (by introducing cellulose nanocrystal, a renewable nanomaterial), and better adhesion of glass beads to the pigmented coating will be advanced. The next stage of the project will focus on scalability issues, both in the production of key coating ingredients and formulations of RDTP systems. One of the key ingredients of the RDTP system is the amine functionalised cellulose nanocrystals (Amine-CNC) needed to induce the aggregation of polymer binders and pigments in the film formation process. Rheological techniques will be used to guide the optimisation of the paint formulations to achieve the correct viscosity profiles for various types of delivery modalities. By working closely with the RDTP formulation team at Ennis-Flint Pickering facility, HQP will be trained, and fundamental knowledge generated from this collaborative research will enhance the technology capability of Ennis-Flint.
