A.uxilia driers do not show catalytic activity themselves, but appear to enhance the activity of the active drier metals. It has been suggested that the auxihary metals improve the solubiUty of the active drier metal, can alter the redox potential of the metal, or function through the formation of complexes with the primary drier. Auxihary driers include barium, zirconium, calcium, bismuth, zinc, potassium, strontium, andhthium. 

Barium. This drier has been used to some extent in Europe as a substitute for lead. Barium 2-ethyIhexanoate [2457-01-4] has been under governmental scmtiny because of its fairly acute toxicity. 

A paint rarely consists solely of pigment dispersed in a solution of a binder. For one reason or another, small quantities of ancillary materials called additives are included. The oldest and still the most important are the driers which are used in all air-drying and many stoving paints containing drying oils. They are organic salts of certain metals, notably cobalt, calcium, barium, zirconium and manganese, with lead very much in decline.

Different drier combinations are recommended for use with high solids aikyds. A study of a variety of driers and drier combinations with high solids coatings has been published (14). Cobalt, neodymium, aluminum, and barium carboxylic acid salts were of particular interest. Performance was enhanced by adding bipyridyl as an accelerator. The author reports that the best drier system was 0.04% Co, 0.3% Nd with 0.07% bipyridyl (percentages based on the vehicle solids). Reference 15 reports studies of mechanisms of action of cobalt and mixed cobalt/zirconium driers. 

UTHOPONE. A mixture of zinc sulfide, barium sulfate and some zinc oxide. Solid lithopone caused mild attack ( 1 mpy) of 3003 and 5154 alloys in laboratory tests conducted under conditions of 100% relative humidity at ambient temperature. Aluminum alloys have been used for pipe lines and driers in the manufacture of lithopone. See also Ref (1) p. 135. (2) p. 433. (3) p. 238, (7) p. 115.
