- Product Benefits
- Low solubility in water, low viscosity in aqueous suspensions and a low acid number
- Suitable as an ”acid donor” for intumescent coatings. Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in DIN, BS or ASTM
- The application of Exolit® AP 423 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 incorporated into the base formulation at the rate of 10 - 20%
- Biodegradable by breaking down to naturally occurring phosphate and ammonia
- Non-halogenated flame retardant with favorable environmental and health profile

- Intumescent coatings
- On account of its low water solubility, Exolit® AP 423 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 DIN, BS or ASTM.
- The application of Exolit® AP 423 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).
- Exolit® AP 423 imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10 - 20 %.
