Ensuring the structural integrity of buildings in the event of a fire is a critical aspect of modern construction. Intumescent coating technology represents a significant advancement in passive fire protection, and at its core lies the versatile chemical, Ammonium Polyphosphate (APP). These specialized coatings, when exposed to high temperatures, swell and expand to form a thick, insulating char layer, protecting the underlying substrate from rapid heat transfer and fire damage.
Ammonium Polyphosphate is a primary active ingredient in these sophisticated systems, making it highly effective for ammonium polyphosphate for intumescent coatings applied to steel, wood, and composite structures. This protective char acts as a barrier, slowing down the temperature rise of the protected material, thereby extending the evacuation time for occupants and allowing fire services more time to bring the blaze under control.
