Abstract
The present invention provides thermosetting aqueous binder compositions of (i) one or more diprimary diamine, e.g. lysine, or poly(primary amine), e.g. polyethylenimine and tris(2-aminoethyl)amine, and (ii) one or more 5-carbon reducing sugar, such as xylose. The binders are at least substantially formaldehyde free and cure rapidly at temperatures sufficiently low and with sufficiently little swelling to enable one to provide wood or woody material containing articles, such as particle board, oriented strand board and bamboo boards or articles.
