clear and red violet liquid.
2. Applications:
cobalt is an extremely active & most widely used drier in coatings & capable of being used even as a single drier. It is primarily an oxidation catalyst & acts as a " surface drier ". It may have a tendency to cause surface wrinkling, hence to provide uniform drying. Cobalt is generally used in combination with other metals, such as manganese, zirconium, calcium & combinations of these metals. As quantity of cobalt drier used is very small, it minimizes discoloration in paints & enamels compared with other driers. Cobalt does not discolor white paints as the deep blue color of the cobalt counteracts the yellow of the oils &resins & thereby enhances the whiteness of the paint. The unique feature of cobalt is that is least affected by atmospheric humidity. Cobalt is an effective accelerator for polyester.
