Abstract
Binder compositions are described that contain (1) a reducing sugar and (2) a reaction product of a urea compound and an aldehyde-containing compound. A specific example of the binder compositions include dextrose and an imidazolidine compound such as 4,5-dihydroxyimidazolidin-2-one. The binder compositions may be applied to collections of fibers and cured to form a fiber-containing composite, such as fiberglass insulation.
