Low volatile organic compound coatings for corrosion protection of steel structures
The overall objective of this collaborative project between Corus, Centra Sviluppo Materiali (CSM) and Arcelor was to assess the performance of low-VOC coating systems compared to their solvent-borne counterparts. Firstly, environmental impacts of low-VOC and solvent-borne coatings were determined using a life cycle assessment (LCA). Secondly, several commercial formulations, including solvent, water-borne, high solids and hybrid, were applied on blast-cleaned, zinc-metallised and HDG steels. Their applicability was compared. Then these coupons underwent accelerated and natural weathering tests to be evaluated for their corrosion resistance. Electrochemical studies were used to explain corrosion mechanism studies. Finally, sensitivity of surface preparation of low VOC systems was also studied for new, as well as flash- rusted and weathered, structures. In conclusion, low-VOC coating systems have shown equivalent or better performances in terms of paint preparation, corrosion resistance and sensitivity to surface preparation compared to the solvent-borne reference systems.
