Abstract
Binder compositions are described that include at least one formaldehyde-containing compound, a cyclic urea-dialdehyde compound, and a polyamine compound. The polyamine compound may be selected from melamine and dicyandiamide. The weight ratio of the at least one formaldehyde-containing compound to the combined weight of the cyclic urea-dialdehyde compound and the polyamine compound may be greater than or about 1:1. As described are binder-containing fiberglass products that include glass fibers and a binder. The binder may include a formaldehyde polymer characterized by crosslinking with a cyclic urea-dialdehyde and a polyamine. The binder-containing fiberglass products have reduced formaldehyde emissions.
