Abstract
A curable aqueous binder composition comprising sheared or extruded cross linked starch particles and a 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 as well as wood based products and construction materials. In one application the curable aqueous starch binder composition may be blended with a second non-formaldehyde resin to make fiberglass insulation. In another application the curable aqueous starch binder composition may be mixed into a formaldehyde based resin to make fiberglass roof shingles.
