This product equivalent to Clariant GmbH's Exolit AP 422, 423 and Budenheim FR Cros 484.

Key properties:

GD-APP101 is a fine-particle ammonium polyphosphate produced by a special method.The pruduct is largely insoluble in water and completely insoluble in organic solvent. It is white, non-hygroscopic and non-flammable, whose crystalline form is II, n>1000.

1, Low water solubility GD-APP101 has low water solubility which makes it useful in application where the product is exposed to high humidity conditions or water.

2, High phosphorus content GD-APP101 contains 72.5% phosphorus (as P2O5) which makes it a very effective fire retardant.

3, Nearly neutral PH-GD-APP101 can be neutralized or brought to the alkaline side by the addition of small amounts od ammonium hydroxide.

4, Non-halogen GD-APP101 is a highly effective non-halogen fire retardant.


1, Solvent based intumescent coatings.

2, Water based intumescent coatings.

3, Flame retardant for flexible and rigid urethane foams.

4, Flame retardant for unsaturated polyesters.

5, Flame retardant for epoxies.

6, Flame retardant for acrylics.

7, Flame retardant for polyurethanes.
