Barium is another auxiliary driers which is used in conjuction with other driers to improve thier performance. Although it exhibits poor performance  when used on its own, it promotes the activity of through drier. As it is adsorbed by the drier adsorbing pigments, it serves as an excellent wetting and dispersing agent especially at severe wheather conditions. The paints with barium as auxiliary driers shows better gloss and minimized loss-of-dry. Barium driers are used in conjuction with surface driers such as cobalt and manganese.
