ABSTRACT:
Combustible materials such as fiber is made flame retardant by treating the material with a methanol or water solution containing the newly discovered compound ammoniumtriborate (NH.sub.4.B.sub.3 O.sub.5.3CH.sub.3 --OH) or a methanolic solution of newly discovered methylborate ammonia adduct. These new flame retardants have the ability to penetrate the combustible material when applied as a solution and thereafter be converted in situ to ammoniumpentaborate to result in enhanced flame retardation over that achieved by merely the direct treatment with ammoniumpentaborate with other borate flame retardants.
