FR CROS® 758

FR CROS® 758 by Budenheim is a phosphorus-based, flame retardant. Intumescent coatings are the ideal fire-protection solution for applications such as paints and coatings on the steel structures of buildings. Ammonium polyphosphates (APP) are key ingredients for intumescent coatings. FR CROS® 758 is an aluminum polyphosphate, which acts as a ceramifying agent at temperatures above 300°C. It is used in combination with ammonium polyphosphate, e.g. FR CROS® 584, to optimize char strength, adhesion and character of the intumescent char. The use of FR CROS® 758 in intumescent coatings improves char performance by increasing insulation and enhancing cell structure homogeneity.
