Oxovanadium(IV) 2-ethylhexanoate and its effect on drying alkyd resins about different oil lenghts

Popis výsledku v původním jazyce

Alkyd resins modified with polyunsaturated fatty acids (e.g. linoleic acid, linolenic acid) are able to provide polymeric film without addition of any curing agents but this process is generally very slow. Therefore, the use of catalysts, so-called driers, is necessary for acceleration of the drying process and improvement of the physical properties of resulting polymeric film. Commercially used cobalt-based driers, e.g. cobalt(II) 2-ethylhexanoate (Co-Nuodex), belong to the most powerful drying agents.However, pronounced toxicity of cobalt(II) compounds stimulate a legislative pressure on the paint-producing industry to replace them with less toxic agents. Oxovanadium(IV) 2-ethylhexanoate was established as a new primary drier for alkyd-based paints.The 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.
