- Product Benefits
- Extremely low water solubility
- Completely insoluble in organic solvents, non-hygroscopic and non-flammable
- Even lower viscosity in aqueous suspension, lower heat stability in the temperature range > 300 °C and improved powder flowability in comparison to Exolit® AP 422 Can be used for all applications where ammonium polyphosphate is suitable
- Can be used advantageously in intumescent coatings where the ammonium polyphosphate is required to have extremely low water solubility and where lower heat stability at temperatures above 300 °C contributes to more rapid foaming of the coating
- 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. The application of Exolit® AP 462 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1)
- Imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20%
- Suitable non-halogenated flame retardant for polyurethane foams
- Excellent flame-retardant effect in cellulose-containing materials such as paper and wood products
- With chipboard products, the B classification according to DIN EN 13501-1 can be achieved by adding 15 - 20%
- Casting resins based on epoxy resins or unsaturated polyester resins achieve the classification UL94-V0
- Non-halogenated flame retardant with favorable environmental and health profile

- Product Applications
- Exolit® AP 462 can be used for all applications ammonium polyphosphate is suitable for. In cases where a specific phosphorus content is required to obtain the desired effect, the lower phosphorus content of Exolit® AP 462 should be compensated by increasing the amount of product added.
- Exolit® AP 462 can be used advantageously in intumescent coatings where the ammonium polyphosphate is required to have extremely low water solubility and where lower heat stability at temperatures above 300 °C contributes to more rapid foaming of the coating.
- Intumescent coatings
- On account of its low water solubility, Exolit AP 462 is particularly suitable as an ”acid donor” for intumescent coatings. Other essential components of intumescent systems include a binder, a carbon donor (e.g. pentaerythritol) and a blowing agent (e.g. melamine).
- On exposure to flame, the intumescent coatings form a carbonaceous foam which effectively shields the underlying material from temperature increases.
- Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in EN, DIN, BS, ASTM and others.
- The application of Exolit AP 462 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).
- Exolit AP 462 imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20 %.
- Polyurethane foams
- Exolit AP 462 is a suitable non-halogenated flame retardant for polyurethane foams. If handling of Exolit AP 462 as a solid is not possible we recommend the dosage of the flame retardant by preparing an Exolit AP 462/polyol-suspension. Because of the low acid number of Exolit AP 462 it is also possible to incorporate this flame retardant in an
- Exolit AP 462/isocyanate suspension. To prevent the solid from settling the Exolit AP 462 suspensions should be stirred or circulated by pump.
- Other applications
- Exolit AP 462 has an excellent flame-retardant effect in cellulose-containing materials such as paper and wood products. With chipboard products the B classification according to DIN EN 13501-1 can be achieved by adding 15 - 20 % Exolit AP 462. Casting resins based on epoxy resins or unsaturated polyester resins achieve the classification UL94- V0 with Exolit AP 462.
