Carbamidfuran and carbamiddianfuran pitches the technology of reception is developed for foundry manufacture resource-saving. As a source of formaldehyde and partially a carbamide it is used carbamidformaldehyd a concentrate. Concentrate use allows to receive pitch with the high maintenance of solids, to exclude a stage evaporation ready pitch, to reduce time of synthesis of pitch and to lower the expense of heat on its reception. The conducted tests of pre-production models of pitch in industrial conditions have shown its suitability for reception sand pitch mixes which apply to manufacturing casting from aluminium.
