Gradient Integrated Layer Additives and Coatings
Multi-layered layered coating systems require complex application and processing procedures that are neither cost effective nor provide optimum properties. Multiple formulation, application and processing steps not only contribute to complexity of the composite system, but also results in unnecessary waste generation, differential properties such as adhesion and corrosion resistance. It would be desirable to reduce the number of layers to a minimum, while providing the same or better overall performance. In this presentation we report the design and development of novel raw materials and coatings that preferentially phase separate in respect to their functionality autonomously or under kinetic and thermodynamic stimuli. The gradient integrated layers allow directing specific material or a layer to migrate to a predetermined location in the coating volume, thereby improving the efficacy of the raw material and the enhanced functionality of the coating layer. As a multi-component coating, it was demonstrated that kinetically controlled reactions aided by incompatible polymers possessing and gradient surface-free energies can afford thermodynamically stable interfaces. Prototype systems were applied, cured and characterized by FTIR, SEM/EDX and were evaluated using standard coating test methods.
