A curable sheared or extruded, cross linked starch nanoparticle latex binder for use with mineral, natural organic or synthetic fibre products and non-woven mats

Liant de latex de nanoparticules d'amidon reticule durcissable cisaille ou extrude pour utilisation avec des produits de fibres minerales, organiques naturelles ou synthetiques et nattes non tissees

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 fibre products including mineral fibre insulation, non-woven mats, fibreglass insulation and related glass fibre 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 fibreglass insulation. In another application the curable aqueous starch binder composition may be mixed into a formaldehyde based resin to make fibreglass roof shingles.
