ABSTRACT:
There is disclosed a process for preparing novel tacking agents for glass fiber insulation. The tacking agent solution is prepared by adding a condensed phosphate to an aqueous solution of aluminum orthophosphate to provide a homogeneous solution having an Al:P molar ratio of less than 1, preferably 1:3 and wherein the amount of condensed phosphate comprises from about 25 to about 75 percent of the total phosphate in the solution. The tacking agent is applied to glass fiber in the preparation of insulating articles and then heated to convert the tacking agent into a non-hygroscopic, water insoluble, amorphous, condensed aluminum phosphate polymer. The tacking agent resiliently tacks the glass fibers together so as to provide regain of shape after deformation of the fibers as by compression.
