ABSTRACT:
Two distinct resin compositions are provided in two physically separated components--one component impregnates a liquid-penetrable article substrate, such as a paper web, to provide a reactive substrate capable of forming a resin cement in situ upon contact with the other component. A first inorganic resin component, hereinafter referred to as component A, is a liquid comprising an aqueous composition of an aluminum phosphate, or a magnesium phosphate or a mixture thereof. A second component, hereinafter referred to as component B, is a liquid comprising an aqueous vehicle; a phosphate-reactive constituent selected from a magnesium oxide source, reactive wollastonite, or mixtures thereof having a relatively low surface area, e.g. dead-burned magnesium oxide having a surface area of about 0.75 m.sup.2 /gm; and a non-reactive phosphate dispersing agent.
