Abstract
The invention relates to an aqueous resin composition and a method for the manufacture of an aqueous resin composition which resin is a reaction product of an oxidised polysaccharide and a crosslinking agent, which oxidised polysaccharide is an oxidised cellulose comprising aldehyde groups, which crosslinking agent comprises two or more groups reactive with the aldehyde groups, wherein the aldehyde groups in the resin in the aqueous resin composition are in hydrated or un-hydrated form and are at least partly converted to inter- or intramolecular hemiacetals, wherein the resin is dispersed and/or dissolved but not gelled. The invention also relates to the use of this composition for a binder in inorganic fibres products.
