REDUCED SALT PRECIPITATION IN CARBOHYDRATE CONTAINING BINDER COMPOSITIONS

Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca.sup.2+, Mg.sup.2+, Ba.sup.2+, Al.sup.3+, Fe.sup.2+, Fe.sup.3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.
