- Products Benefits
- Non-halogenated flame retardant with favorable environmental and health profile
- Greatly reduced water solubility, low viscosity in aqueous suspension, very low acid number
- 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. Their application 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. PUR Foams with Exolit® AP 422 can be recycled
- Excellent flame-retardant effect in cellulose-containing materials such as paper and wood products. With chipboard products, the DIN EN 13501-1 classification can be achieved by adding 15 - 20 % Exolit® AP 422
- An essential component in intumescent formulations for thermoplastics, particularly polypropylene, for which the classification UL 94-V0 is specified for applications in the electrical sector
- In the case of thermosets like epoxy resins and unsaturated polyester resins, it paves the way for the production of lightweight components with low solids content
- Biodegradable by breaking down to naturally occurring phosphate and ammonia
- Performance Advantages:
- Constant high quality and hydrolytic stability
- Supports the attainability of eco-labels for customer products

- Intumescent coatings
- On account of its low water solubility, Exolit® AP 422 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, 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 422 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).
- Exolit® AP 422 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 422 is a suitable non-halogenated flame retardant for polyurethane foams. If handling of Exolit® AP 422 as a solid is not possible we recommend the dosage of the flame retardant by preparing an Exolit AP 422/polyol-suspension. Because of the low acid number of Exolit® AP 422, it is also possible to incorporate this flame retardant in an Exolit AP 422/isocyanate suspension.
- To prevent the solids from settling, the Exolit AP 422 suspensions should be stirred or circulated by pump. The stirrers commonly found in service tanks are adequate for this purpose.
- Other applications
- Exolit® AP 422 has an excellent flame-retardant effect in cellulose-containing materials such as paper and wood products. With chipboard products, the DIN EN 13501-1 classification can be achieved by adding 15 - 20 % Exolit® AP 422.
- Because of its high heat stability, Exolit® AP 422 is an essential component in intumescent formulations for thermoplastics, particularly polypropylene, for which the classification
- UL 94-V0 is specified for applications in the electrical sector.
- Casting resins and composites based on epoxy resins or unsaturated polyester resins achieve the classification UL 94-V0 with Exolit® AP 422. Combinations of AP 422 with
- ATH show synergistic effects in UL94 and LOI tests.
