The material can vary in viscosity from a putty that is moldable or trowelable into place to a thin paste that can be sprayed to form a flexible and stable fire stop seal or coating. The material with essentially no shrinkage retains strength and adhesion qualities before and after exposure to fire and retains superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire.Field of SearchIntumescent coating or ablative composition or process of preparingIngredient is asphaltic, bituminous, or water settable inorganic material, e.g., cement, plaster of Paris, etc. Ingredient contains a silicon atom Ingredient contains a metal atom Ingredient is water settable inorganic composition Ingredient contains a silicon atom At least one polymer is derived from reactant containing two or more three membered heterocyclic rings having two carbon atoms and one chalcogen atom or polymer-forming system contains the same type of reactant At least one polymer is derived from an aldehyde or derivative or wherein the polymer-forming system contains the same type of reactant At least one polymer is derived from a -N=C=X reactant wherein X is a chalcogen atom or wherein the polymer-forming system contains the same type of reactant At least one polymer is derived from a polycarboxylic acid or derivative and a polyol or wherein the polymer-forming system containing the same type of reactants NONURETHANE FLAMEPROOFED CELLULAR PRODUCT POLYURETHANE CELLULAR PRODUCT CONTAINING UNREACTED FLAME-RETARDANT MATERIAL | |
