ABSTRACT:
Fire-retardant compositions consisting essentially of an inorganic, fire-retardant phosphate salt and a binder of a poly-2-oxazoline having a weight average molecular weight of at least about 1,000 and at least about 40 percent phosphorylated are applied to wood or wood products by an improved method comprising admixing with a solution of the composition, either prior to or simultaneously with the application of the composition to the wood or wood product, an anionic or nonionic organic phosphate ester surfactant, such as Victawet.RTM. 35B. The use of these surfactants increases the rate and extent of penetration of the fire-retardant composition into the wood.
