Abstract
The present invention provides thermosetting aqueous binder compositions comprising one or more reducing sugar, one or more diprimary diamine or poly(primary amine), and from 7 to 45 wt. %, based on total solids, of one or more polysaccharide having a dextrose equivalent (DE) value of from 5 to 30. The compositions provide treated articles, such as fiberglass mat. The binders provide articles having a dramatically reduced binder weight loss upon cure and a reduction in cure energy needed to achieve early dry strength.
