Brief: Ever wondered how high polymerization ammonium phosphate creates effective fire protection? This video demonstrates how TF-201 acts as an acid donor in intumescent coatings, showing the carbonaceous foam formation process that expands to shield materials during fire exposure and meet international safety standards.
Related Product Features:
  • Acts as an acid donor in intumescent coatings for effective fire protection.
  • Forms a carbonaceous foam that expands several times when exposed to flame.
  • Helps steel structures meet fire resistance classes in EN, DIN, BS, and ASTM standards.
  • Features high decomposition temperature above 275°C for thermal stability.
  • Low solubility in water with less than 0.45% solubility at 25°C.
  • White powder appearance with controlled particle size of 15-25µm.
  • Contains high phosphorus content with ≥71% P2O5 and ≥14% nitrogen.
  • Maintains neutral pH range of 5.5-7.5 in aqueous solutions.
FAQs:
  • What is the primary application of TF-201 High Polymerization Ammonium Phosphate?
    TF-201 is primarily used as an acid donor in intumescent coatings, where it helps form a protective carbonaceous foam when exposed to fire, expanding to shield underlying materials from heat and flames.
  • What fire resistance standards can be met using this fire retardant?
    Steel structures coated with intumescent paints containing TF-201 can meet the fire resistance classes specified in international standards including EN, DIN, BS, ASTM, and others.
  • What is the decomposition temperature and why is it important?
    TF-201 has a high decomposition temperature above 275°C, which is crucial for maintaining stability and effectiveness during fire exposure, ensuring the intumescent coating activates at the right temperature to provide protection.
  • How does the solubility property affect its performance in coatings?
    With low water solubility of less than 0.45% at 25°C, TF-201 remains stable in coating formulations and doesn't leach out, ensuring long-term fire protection performance even in humid conditions.
