Aluminum Oxide Nanocomposite Wax Powders as PTFE Replacements
"Micronized wax powders can be highly engineered materials that are engineered to deliver a specific function to the surface of a coating. With proper design, the mobility of the wax particle can be optimized to efficiently stratify at the surface, where physical durability properties such as scratch resistance are required.
This paper will present a novel, patent-pending approach to wax additive design based on multicomponent composites containing nano-scale aluminum oxide particles. Data will be presented to show the dramatic improvement in surface scratch resistance vs. the unmodified wax powder. Data will also be presented to demonstrate that a wax/aluminum oxide nanocomposite powder is actually a more efficient way to bring the aluminum oxide to the coating surface, as compared to directly formulating aluminum oxide into the coating."
