Melamine formaldehyde resin coated APP-II is a flame retardant based on phosphorus and nitrogen synergism, for short MF coated APP.

The type is TF-MF201. It is a fine particle white free flowing powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents and it is non-hygroscopic and non-flamemable. Even lower viscosity in aqueous suspension, lower heat stability in the temperature range >300℃ and improved powder flowability in comparison to ordinary APP phase II (TF-201).

Advantages
1. Non-halogenated flame retardant, green and environmental protection

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

Application

1. Can be used for all applications where the ammonium polyphosphate is suitable
2. Particularly suitable as an ”acid donor” for intumescent coatings thanks to its low water solubility. Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in EN, DIN, BS, ASTM and others.
3. It can be used advantageously in tumescent coatigns where the ammonium polyphosphate is required to have extremely low water solubility and where lower heat stability at temperatures above 300℃ contributes to more rapid foaming of the coating, such as cable coating.
4. Imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20%
