Comparison of drier production methods showed that selection
of method depends on the raw materials, transportation,
desire metal content of drier, and tendency to have a facility
for production monitoring. Thanks to good electron releasing power of amines, they were the best choice for increasing the
efficiency of driers.
Although modification of cobalt drier reduced the
amount of cobalt consumption and consequently could help
environmental protection, many efforts are essential to use
environmentally friendly driers instead of cobalt drier.
