Abstract
A curable aqueous binder composition includes a dispersion of biopolymer particles, optionally with and an inter-particle crosslinking agent, for use in the formation of composite materials such as mineral, natural organic, or synthetic fiber products, including mineral fiber insulation, non-woven mats, fiberglass insulation and related glass fiber products, and wood based products, and construction materials. In an application of the curable aqueous composition to making fiberglass insulation, the composition may be blended with a second resin which may be a non-formaldehyde resin. In an application of the composition to making fiberglass roofing shingles, the biopolymer particles may be mixed into a formaldehyde based resin during or after the polymerization of the resin.
