Symbol Metal content DRIERS Product name Description MORDRY Barium 12.5 Ba Barium carboxylates improve through-drying of a coating and have good pigment wetting characteristics. They also demonstrate lower water sensitivity than Calcium carboxylates. Barium carboxylates improve gloss and prevent adsorption of the primary driers at the surface of the pigments and extenders, thus increasing the stability of the coating during prolonged storage. In combination with Cobalt, Barium has a similar effect to that of Lead MORDRY Barium 10 WD Ba MORDRY Barium 10 WD is an auxiliary drier for all water-reducible oxidatively drying alkyd paints. Excellent results can be achieved when using MORDRY Barium 10 WD together with other waterdispersible metal driers such as MORDRY Cobalt 6 WD, MORDRY Zirconium 12 WD or MORDRY Manganese 6 WD MORDRY Calcium 4 Ca Calcium carboxylates, by themselves, have minimal effectiveness as driers but are very useful when used in combination with active driers such as Cobalt and Manganese. Calcium driers help to improve hardness and gloss as well as to reduce skin formation, silking and blooming. They are also useful as pigment wetting/dispersing agents and loss-of-dry inhibitors 12.5% 10% 4% MORDRY Calcium 5 Ca See MORDRY Calcium 4 5% MORDRY Calcium 10 Ca See MORDRY Calcium 4 10% MORDRY Calcium 4 WD Ca MORDRY Calcium 4 is a water-dispersible Calcium salt of saturated branched mixture of acids. Excellent results can be achieved when using MORDRY Calcium 4 together with other water-dispersible metal driers MORDRY Cerium 10 Ce Cerium carboxylates promote the polymerization and through-drying processes. They are particularly recommended for baking enamels and white and clear overprint varnishes, as they produce less discoloration than other active metals. Cerium driers are far less active than cobalt and manganese. At low temperatures (below 0º C) or at very high atmospheric humidity, Cerium driers do though show higher efficacy than the other primary driers MORDRY Coblat 6 Co Cobalt carboxylates are the most effective oxidative catalysts at ambient temperatures. Cobalt is a primary drier for coating systems. Cobalt soaps function as oxidation catalyst and are used at low levels. The use of excessive amounts of cobalt in coating systems can cause rapid skinning, wrinkling of the film as it dries, and reduced water resistance of the cured film MORDRY Coblat 10 Co See MORDRY Cobalt 6 10% MORDRY Coblat 12 Co See MORDRY Cobalt 6 12% MORDRY Cobalt 6 WD Co MORDRY Cobalt 6 WD is a water-dispersible Cobalt salt of saturated branched mixture of acids. Excellent results can be achieved when used together with other water-dispersible metal driers 4% 10% 6% 6% MORDRY Cobalt 6 P Co The curing of unsaturated polyester requires organic peroxide which starts polymerization by radical formation.

Metal-organic compounds (metal soaps or complex) are used in relatively small concentrations to control drying processes. Such additives are described as driers. From the chemical standpoint, driers are molecular (homophase) catalysts for free radical oxidative polymerisation, which is a chain process developing in the presence of the atmosphere oxygen. 8
DRIERS Metal ions are active ingredients of driers, and organic portion of their molecules determines largely whether the drier will meet its basic requirements which are: Good solubility and high stability in various kinds of binders Good storage stability of the drier Ability to be present in a high metal concentration Sufficiently low viscosity, to make the handling of the drier easier Optimal catalytic effect of the drier Best price/performance relation DELTA specialties offer a broad range of driers (single metal and mix driers) to help you control the drying time of your formulations. 9
