Films may develop a brown colored hue on ageing due to the color of the manganese drier.
"Accelerated" manganese driers improve the activity somewhat but may affect the color of light tinted coatings over time and generate brittle films.
First of all, the performance of the commercial cobalt driers and manganese driers were analyzed; the effect of bipyridine inclusion on the reactivity of these driers has been investigated and the results compared with the actual effectiveness of these systems in real alkyd paints.
(29,30) The drying times for [Mn(acac)[.sub.3]] and [Mn(acac)[.sub.3]]/bpy and the results obtained for the commercial combination of cobalt driers and manganese driers are listed in Table 2.
The rates of disappearance of EL in the reaction with dioxygen, as catalyzed by the commercial cobalt driers and the manganese driers, correlate reasonably well with the actual drying times as found in the real alkyd paints.
[Mn(acac)[.sub.3]] also functions as a very good drying catalyst in a real alkyd system, better than conventional manganese driers and comparable with, or even better than a cobalt combination drier.
