Oxovanadium(IV) 2-ethylhexanoate was established as a new primary drier for alkyd-based paints. A series of experiments has demonstrated an excellent drying activity toward solvent-borne alkyd resins of different oil length at considerably lower metal concentration than optimal for commercial cobalt(II) 2-ethylhexanoate. The behavior in real paint was simulated on formulations bearing inhibitor of autooxidation. The detailed studies of the drying process have shown that the relatively slow initial step of autooxidation reaction, when compared with cobalt compounds, is compensated for by the absence of the induction times. Furthermore, the active oxovanadium(IV) species are not consumed during the drying processes as evidenced by EPR spectroscopic measurements.

2-ethylhexanoatu oxovanadičitý vykazuje vlastnosti typické pro primární sikativy. Uvedené experimenty ukazují výbonou sikativační aktivitu vůči alkydovým pryskyřicím různé olejové délky při výrazně nižších koncentracích než je běžné u komerčních 2-ethylhexanoatu kobaltnatého. Chování v reáné formulaci bylo simulováno na sysytémech s inhibitory autooxidace.
