Exolit® AP 422 A

Exolit® AP 422 A by Clariant is a non-halogenated flame retardant with favorable environmental and health profile. It is a fine-particle ammonium polyphosphate (phase II) with less than 0.1% melamine. It is colorless, non-hygroscopic, non-flammable and free of SVHCs. It has low viscosity in aqueous suspension, very low acid number.

• It is suitable as an acid donor for intumescent coatings due 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.
• Its application on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).
• Exolit® AP 422 A can be used in transport applications to obtain good fire, smoke, and toxicity results.
• It is biodegradable by breaking down into naturally occurring phosphate and ammonia.
• It has a shelf life of 12 months.
