MF Coated APP Ammonium Polyphosphate With Extremely Low Solubility For Intumescent Fire Retardant Paint For Steel

MF Coated APP Ammonium Polyphosphate With Extremely Low Solubility For Intumescent Fire Retardant Paint For Steel

TF-MF201 is melamine-formaldehyde resin coated type based on TF-201 APP phase II. 

With the MF coat, the advantage of TF-MF201 is the extremely low water solubility even in high-temperature water. Benefits this advantage, it's widely used in intumescent steel paint, especially in the weather-resistant situation.

Advantages
1 . Extremely low water solubility
2 . Completely insoluble in organic solvents, non-hygroscopic and non-flammable
3 . Even lower viscosity in aqueous suspension improved flowability

4 . Non-halogenated flame retardant with favorable environmental and health profile

Application

1. Can be used for all applications where the ammonium polyphosphate is suitable
2. Can be used advantageously in intumescent coatings where the ammonium polyphosphate is required to have an extremely low water solubility
3. Particularly suitable as an ”acid donor” for intumescent coatings thanks to its low water solubility.

4. Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in EN, DIN, BS, ASTM and others.
5. Imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20%
