Intumescent Compound

Mcr Polylack K

  • Intumescent compound
    mcr Polylack K, when applied as a coating or filler, reacts to high temperatures.
  • Protective carbon layer
    It forms a thermo-insulating foamed carbon layer that halts the combustion of polymer insulation at an early stage.
  • Effective fire barrier
    Prevents the spread of flames on the protected surface.
