Manganese. This drier, sold normally in strengths of 6, 9, or 12 percent metal, is what is known as a through drier, acting on both the top and the bottom of the film. Mainly, however, it is an oxidation rather than a polymerization catalyst and can therefore cause wrinkling if employed in excessive amounts.  2, record 1, English, - manganese%20drier

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.  2, record 2, English, - cobalt%20drier

Organometallic complex catalysts tend to be highly active, specific, and selective, and may resist poisoning better than heterogeneous systems. The catalytic center may have two metal sites. Organometallic catalysts have a central transition-metal atom or ion bonded to molecules known as ligands which form a polyhedron around the metal. The nature of the metal and ligands critically influences the electronic structure of the complex. The coordination bonding properties of the metal are a key feature of the catalytic complexes. Important reactions of catalyst complexes are ligand exchange, oxidative addition, and the insertion reaction.  1, record 13, English, - organometallic%20catalyst

The action of the metallic catalyst has for many years been related to the geometric spacing and arrangement of the metal atoms with respect to the molecules of the reactants. Thus, for example, Beeck found that a plot of the spacing of the atoms of pure metal films against the activity of these films for the hydrogenation of ethylene yielded a curve with a maximum corresponding to activities larger by several orders of magnitude than the activity of some metals lower on the curve. Thus, a thin film of rhodium was, per unit area at a given temperature, about 1000 times as active as a thin film of nickel.  1, record 14, English, - metallic%20catalyst
