VANADIUM-BASED DRIER SUITABLE FOR ALKYD PAINTS

Popis výsledku v původním jazyce

Alkyd resins are the most important binders for air-drying paints but their drying mechanism is relatively slow. The drying process can be accelerated by driers. Preferably complexes of transition metals, which exhibit an energy-undemanding single-electron redox transition, can be used as driers. Cobalt-based driers are the most common and highly active. However, these compounds exhibit carcinogenic effects. Because of that reason, there is demand to find less toxic or nontoxic driers. A vanadium-containing compound appears to be a suitable alternative. The drying times were measured for the comparison of the drying activity of the commercial driers VP 0132 and Co-Nuodex in solvent-borne alkyd resins of different oil lengths. It has been found that vanadium-based alkyd formulations have a high efficiency at lower metal concentrations than the cobalt driers.
