TU 38.401-67-108-92, GOST 443-76
NEFRAS-C2-80/120 solvent is a low-boiling, clear, and colorless fraction of dearomatized catalytic reforming gasoline. The product belongs to mixed-type solvents and is characterized by a high evaporation rate, the absence of a pungent unpleasant odor, as well as minimal sulfur and aromatic hydrocarbon content. In industrial and everyday practice, this solvent is widely known under its historical name “Kalosha” gasoline (or “Galosha”) due to its primary large-scale application in the rubber industry.
Thanks to its chemical purity and excellent dissolving properties, NEFRAS-C2-80/120 is indispensable in many industries:
– Rubber Industry: The primary raw material for the production of high-quality rubber adhesives, mastics, and other rubber goods;
– Surface Degreasing: Deep cleaning and preparation of metals, electrical equipment, fabrics, leather, and plastics before bonding, sealing, or painting;
– Auto Service and Repair: Effective washing of parts (bearings, transmission units, engine elements), removal of bitumen stains and factory automotive preservatives;
– Paint and Coating Production: Dilution of special oil paints, bitumen paints, enamels, and varnishes to the required viscosity;
– Household Use and Tourism: Effective and safe fuel for catalytic heaters, petrol lighters, blowtorches, and camping stoves.
