Formaldehyde-free binder compositions are described that include an aldehyde or ketone, a nitrogen-containing salt of an inorganic acid, and an acidic compound. The acidic compound may be an organic acid, such as maleic acid or citric acid among others. The acidic compound is supplied in quantities that lower the pH of the binder composition to about 5 or less. The binder compositions may be used in methods of binding fiberglass and the resulting fiberglass products have an improved tensile strength due to the addition of the acidic compound.

The present invention concerns an aqueous flame retardant composition for mineral fiber-based mats, in particular glass or rock fibers, which comprises: at least one thermoplastic or thermoset resin; magnesium hydroxide, Mg(OH).sub.2, and aluminum hydroxide, AlOOH, as flame retarding agents; and optionally, carbon black.

It also concerns mats treated with said flame retardant composition.
