KERAFIX^® Cooling-Strip F offers outstanding cooling properties in case of fire, extending the fire resistance duration of fire protection constructs. KERAFIX^® Cooling-Strip F is made of minerals which absorb large amounts of heat once an activation temperature of approx. 100 °C is reached and release approx. 26 % of water of crystallisation. The application of KERAFIX^® Cooling-Strip F and its special 2K variant coated on one side with KERAFIX^® Flexpress 100 (ablative and intumescent) provides solutions with fire resistance periods from 30 minutes to over 90 minutes for wood, aluminium and steel constructs.
