Dunit LLC (Ukraine) is a trader in the sale of powdered lignosulfonates in Ukraine, CIS countries, Europe and Asia.



Technical lignosulfonates - the final product of processing sulfite liquor in the pulp and   paper industry, which is one of the byproducts of the sulfite boiling process for wood pulp.

Applications technical lignosulfonates:

  • In foundry industry as a binder in the manufacture of core and molding compounds in iron, steel and nonferrous casting and in the composition of non-stick paint, in the production of non-ferrous metals as flotation reagent and binder for briquetting fine raw materials;

  • In oil industry in drilling oil and gas wells, as a reagent for regulating the basic parameters of drilling muds, as a component of gelling systems for regulating filtration flows and limiting water inflow in the processes increasing oil recovery;

  • In production of refractory materials as a temporary binder;

  • In construction industry as a diluent cement raw slurry in the production of cement wet method to reduce sludge moisture as a plasticizer of concrete and cement, as the plastifying and adhesive material in the production of gypsum board, chipboard, fiberboard and plywood as a corrective additive in the manufacture of expanded clay gravel, as a binder increased water resistance for dust removal and strengthening of soil in road construction and transport in the mine workings;

  • In chemical industry in the manufacture of pesticides and seed disinfectants, in production of plant protection chemicals as a dispersant and suspension stabilizer;

  • In granulation of carbon and porous fillers from powder, granular materials, charges;

  • In agglomeration of ferrous metal ores and briquetting fine coal fractions and special coke, the manufacture of silicoaluminum briquettes;

  • In production of synthetic tanning agents in the feedstock and the dispersant;

  • As a sizing agent cellulose containing bases in textile industry.

The method of preparation of liquid lignosulfonates out of powdery LST

To make liquid lignosulfonates containing approximately 50% of dry substances out of powdery one, it is necessary to take 50 parts of powder with the moisture of 4% and 46 parts of water. For better powder dissolving heated water at temperature of 40-50°С should be used.
