Abstract

La présente invention concerne des revêtements de protection contre le feu du type expansif et est destinée, par exemple, à la protection anti-incendies d'installations de câbles, comme dans les centrales nucléaires (CN) ou thermiques (CT), afin d'augmenter la résistance limite au feu de structures métalliques porteuses, d'augmenter la résistance limite au feu d'armoires de ventilation, de câbles et de lignes de câbles, y compris dans des CN et des CT, des finitions de structures résistant au feu de sites industriels et de construction, y compris dans des CN et des CT. Le résultat technique de la présente invention consiste en la formation d'une composition expansible à durcissement à froid pour des structures métalliques, laquelle possède une adhérence accrue sur les métaux et divers revêtements d'amorce, du coke cellulaire formé lors du processus de chauffage, et possède une résistance mécanique accrue en cas d'incendie par rapport aux compositions connues.
