Abstract:
The invention provides aqueous thermosetting binder compositions exhibiting both of improved flame retardation and wet tensile strength comprising a reducing sugar, a diprimary diamine or a polyprimary diamine, a phosphorus acid salt and from 3 to 20 wt. %, based on total solids, of an aqueous polymeric polyacid solution polymer containing phosphorus or its salt, wherein the aqueous thermosetting binder composition comprises from 0.7% P (s/s) to 5% P (s/s).
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.
