Iron-based driers are dark red-colored solutions of metallic soap with 2-ethyl hexanoic acid in aliphatic solvents. Although iron do have poor performance at ambient temperature, it has activity at elevated temperature and therefore used as primary drier specifically in baking-stoving systems. Their dark colour limits their use only in dark-coloured baking systems. Iron-based driers find use in anti-corrosion coatings and aluminium paint as a replacement of lead.
