Abstract

This invention relates to a composition suitable for use as a combination fire retardant, soil and water protectant, and biocide, and to the method of making and applying the composition. The preferred embodiment contains the following ingredients: from 2.30% to 9.22% by total weight of ammonium phosphate, monobasic; from 2.30% to 9.22% by total weight of ammonium phosphate, dibasic; from 2.30% to 9.22% by total weight of a compound comprising approximately 50% ammonium polyphosphate, 3% urea, and 47% water; from 2.60% to 10.4% by total weight of a fluorinated acrylic polymer; from 0.025% to 0.1% by total weight of coco imidazuline dicarboxylate; from 1.00% to 4.00% by total weight of organotin; and from 57.84% to 89.475% by total weight of water. The composition is applied to porous materials, such as fabrics, wood, cardboard, or fiberboard, for protection from fire, soil and water damage, and virus and fungus growth. The composition may be applied by spraying it onto the materials or by dipping the materials into the composition.
