Colorbond Meets Nanotech: Understanding Coating Interactions with the Environment

A continual testing development program for Colorbond, a prepainted steel product carefully designed multilayer system that offers corrosion protection and theoretical studies of the material's performance at the nanoscale are conducted. Results suggest that increasing the hardness and atomic roughness of the polyester surface by crosslinking and/or carefully chosen nano-functionalisation can significantly decrease its interactions with the carbonaceous solids and nanoparticles.
