| Usage: | Intumescent coatings On account of its low water solubility, APP-1 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 APP-1 based intumescent coatings on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1). APP-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 %. Polyurethane foams APP-1 is a suitable non-halogenated flame retardant for polyurethane foams. If handling of APP-1 as a solid is not possible we recommend the dosage of the flame retardant by preparing an APP-1/polyol-suspension. Because of the low acid number of APP-1, it is also possible to incorporate this flame retardant in an APP-1/isocyanate suspension. | |
