Zusammenfassung:The mixture, suitable mainly for slightly complicated moulds and cores consists of 100 weight parts of opening material, 0.01 to 0.25 weight parts of naphthalene or octoate of cobalt, vanadium, or manganese and of organic binding agent, and eventually of 0.2 to 1.8 weight parts of iron oxide. It also contains from 0.1 to 2.6 weight parts of liquid polybutadiene with average number molar weight of 1,500 to 10,000 g.moles containing at least 35 percent by weight of 1.2 addition, which has all the chains terminated with hydroxyl groups. The mixture can also contain methyl-tertiary butyl ether for coating the grains of the opening material and in cores with large width it can contain also sulphur, zinc diethyldithiocarbamate and stearin.
