Abstract: A method for coating a fire-resistant substance onto a carrier veil and products containing fire-resistant substances are provided. The method includes delivering a pliable carrier veil in a traveling web, drawing the carrier veil web through a reservoir defined by a nip of two rollers and containing the fire-resistant substance, where the carrier veil is coated with the fire-resistant substance. The method also includes controlling the amount of fire-resistant substance on the carrier veil web by setting a nip dimension between the two rollers, passing the carrier veil through the nip of the two rollers and providing the fire-resistant substance as a slurry suitable to coat the veil exiting the nip with a layer effective to provide a selected fire resistance. Heat is applied to the carrier veil sufficient to accelerate a curing reaction in the fire-resistant substance.
