A paint additive is being designed to respond to its own scratches
University of Queensland researchers are developing tiny containers that release rust-inhibiting molecules when a protective coating is damaged.
The 16 September report describes particles that can be added to water-based paint to protect steel. The self-repairing approach is under development. Claims about much longer protection are research projections and test results, not proof that a real bridge has already stayed rust-free for centuries.
