The cobalt drier, sold containing 6 or 12 percent cobalt as metal, is the most powerful drier used by coatings industry. It acts as an oxidation catalyst and is known as a top drier, drying the top of the film. Excessive amounts of cobalt drier will set up stresses and strains in the paint film that can result in wrinkling. Though purple in color, cobalt has low tinting strength and will not discolor a paint.
