Beschreibung
Zusammenfassung:	An aqueous fire barrier composition comprising: a) latex comprising a polymer; b) a polyol having 2, 3 or 4 hydroxy groups; and c) an intumescent agent comprising a composition comprising granular alkali metal silicate represented by the formula M 2 O:XsiO 2 in which M is an alkali metal, at least one oxyboron compound selected from the group consisting of boric acid and borate salts of Group I and Group II elements, and water bound to said alkali metal silicate, the weight ratio X ranging from about 1.5 to about 4, the molar ratio of boron to M being from about 0.2 to about 0.9, and the water being about 5% to about 15% of the total granule weight.
