Halogen Free Flame Retardant Ammonium Polyphosphate Phase II


When the temperature is within 250℃ , the property of steel changes very little. When the temperature reaches above 300℃ , the strength gradually decreases . When the temperature reaches 450℃ to 650℃, the strength usually drops to zero only in about 15 minutes . Therefore , the steel structure must be coated with intumescent coating to improve its fire resistance limit to meet the requirements of building design .


Intumescent coating is popular in the markeet because of the thin thickness and excellent dcoration effect.


The theory of fireproofing :


Insulation effect and the heat transfer is stopped by intumescent carbon layer .

Heat absorption because of the intumescent process , it will absorb lots of heat during the process of softening , fusion , evaporation and form the carbon layer .


Ammonium polyphosphate (TF-201) is usually working together with melamine and pentaerythritol .

Ammonium polyphosphate (APP) as acid donor , Melamine (MEL) as gas donor and Pentaerythritol (Penta) as carbon donor , these three factors are composed of an intumescent flame retardant system.


TF-201 is suitable for water based and solvent based coatings with difference addition volume and formular . If you need reference furmular , pls contact us freely .
