Organosilicon varnish KO-075

Extended name:  Polymethylphenylsiloxane resin solution, modified with pentaphthalic varnish, in organic solvent (toluene, xylene, solvent-naphtha)
Synonyms:  Siliconorganic varnish type KO-075; Organosilicon varnish KO-075
№ UN:  1263
H.S. Code:  3208 90 910 0
Main applications: 
  • in production of enamels, paints of general use. Mixture of penthaphthalic, perchlorovinyl, nitroenamels with varnish KO-075 improves their strength, water-, heat- and- light resistance, water repellency, gloss and rigidity;
  • in production of heat resistant enamel used to coat parts operating at temperature up to 500 °C;
  • to prevent from corrosion outward surfaces of gas-conduits, chlorinators, steam and gas turbines, ejectors, different units of agricultural machines, air-driers, chemical traps, coal-tar chemical industry equipment;
  • for painting motor radiators and other parts and equipment operating at temperature 350 - 400 °C;
  • as anticorrosive coating of inner surfaces of steam and water tanks operating at temperature 150 - 160 °C;
  • for sizing and finishing of artificial leather; to improve acid resistance of protective clothes, to improve rigidity, heat-and-wear resistance of filtering fabrics;
  • as a separating covering in production of glass and plastics.
