ABSTRACT:
A method of preparing an aqueous resinous system, and the resinous system produced by the method is described wherein about 75-100 parts of an aldehyde such as formaldehyde, about 100-125 parts of phosphoric acid, about 15-25 parts of an alkanolamine such as triethanolamine, about 30-50 parts of urea, and about 20-40 parts of melamine, based on 100-200 parts of water, are reacted to provide an aqueous resinous solution which will cure at room temperature or upon application of heat, permitting its use as a flexible, pliable, waterproof, nonburning coating, especially for textiles and paper containing materials. The solution may be applied by impregnation or as a coating to the fabric or an underlayer to the fabric. In a special embodiment, there is provided a method for providing fire retardancy to a textile fabric applied over an underlayer such as muslin, by applying a fire retardant solution to the underlayer. There is also provided a fire retardant spray solution.
