Abstract
Novel smoldering suppressing compositions containing a metal complex of ammonium superphosphoric acid and having a high phosphate content, and processes for their preparation, are disclosed. Further disclosed are formulations containing these compositions and articles-of-manufacture having these formulations applied thereon. These novel formulations are particularly effective as smoldering suppressants for textiles, and are characterized by a high washing fastness.
Claims63
A smoldering suppressing composition comprising a water-insoluble complex which consists of a multivalent metal and an ammonium salt of superphosphoric acid, wherein said complex contains PO43− in an amount of at least 60 weight percents.
A smoldering suppressing composition comprising a water-insoluble complex which comprises of a multivalent metal and an ammonium salt of superphosphoric acid, the composition being in a form of a dry gellable powder which forms a gel upon contacting an aqueous solution, or, when the composition further comprises an aqueous solution, the composition is in a form of an amorphous gel.
