Exotherm suppressant compositions are described that include a resin, such as a thermoset or thermoplastic resin, and at least one cyclic urea compound. Such compositions have no free formaldehyde, contain no antimony and are halogen free, for example. As described, such compositions can be used as binders, for example, to bind organic, inorganic fibers, and/or minerals. Also described are binder-containing fiberglass products that include glass fibers and a binder. The binder-containing fiberglass products have reduced formaldehyde emissions.
