Why is Colorbond steel greener on the other side of the fence? Designing additives to retard weathering of surface coatings

Grant


Scheme


  • Linkage Projects

Abstract


  • COLORBOND® steel is the flagship pre-painted steel product of BlueScope Steel Limited. Addition of hindered amine light stabilizers (HALS) to COLORBOND® steel paints has been shown to further improve the aesthetic durability of the product in-service. We propose to develop a chemical â¬Ümechanistic modelâ¬" to rationalize both the prophylactic effects of HALS and the reasons for their loss over time. A synergistic combination of electron spin resonance spectroscopy and mass spectrometry to detect, quantify and structurally characterize HALS, related compounds and intermediates in the complex paint matrix will provide this detailed knowledge, enabling design and synthesis of HALS specifically tailored to coil-coated steel applications.
