  • Patent number: 6001285
    Abstract: Intumescing materials for the fighting of fire or the prevention of damage resulting from fires are, as a rule, packaged in cartouches, from which they are removed for processing at building sites or the like. Their processing ability is limited because they harden to a rubberlike state with time. However, according to the invention, their spreading ability is maintained when a specific amount of a cellulose is added to the material.
