Heat-resistant silicone resin KO-075

Product description

Heat-resistant silicone resin KO-075


Heat-resistant silicone resin KO-075 is a solution of a polyester-modified polymethylphenylsiloxane resin in toluene and xylene.



Paintwork materials manufacturing:

  • Heat-resistant enamel KO-835 production. It is prepared by mixing 94 wt. fraction of the resin KO-075 and 6 wt. fraction of aluminum powder. Enamel KO-835 is used to cover parts operating at temperatures up to +500°C.
  • When combining pentaphthalic, perchlorovinyl, nitro-enamels and other types of enamels with resin KO-075, their strength, water resistance, thermal resistance, light fastness, hydrophobicity, gloss and hardness increase.
  • Nonstick paints component.

Corrosion protection:

  • external surfaces gas flues, chlorinators;
  • surfaces of steam and gas turbines, ejectors;
  • various units of agricultural machines;
  • air drying devices;
  • chemical recovery equipment;
  • coke-chemical equipment;
  • internal surface of steam-water tanks operating at a temperature of +150°C - +160°С.
  • for the painting of car radiators;
  • for the painting of equipment and other parts that operating for a long time at a temperatures of +350°C - +400°C.

Oil fields:

  • protection of ladders, gas separators with all fittings, cyclone separators.

Light industry:

  • faux fur sizing and finishing;
  • manufacture of acid-resistant clothing;
  • impregnation of filter fabrics by heat-resistant silicone resin KO-075 increases strength, heat-resistance and wear-resistance.

Production of glass and fiberglass plastics:

  • as a release (separation) coating.


  • Combines good heat resistance and resistance to atmospheric conditions.
  • Good compatibility with organic resins and enamel components.
  • The varnish film has good oil and petrol resistance.
  • The polymerized film is non-toxic, fireproof.


Store in a sealed container at a temperatures from -30ºС up to +40°С. Store in a cool, dry, well-ventilated place, away from areas from heaters. Protect from moisture and direct sunlight.
