Claims13
A binder composition comprising a polymeric product of at least one carbohydrate component and at least one amine component, wherein the at least one amine component comprises a substituted or unsubstituted primary diamine and/or a substituted or unsubstituted primary triamine.
A binder composition comprising a water-soluble pre-reacted binder and at least one second amine component,
- wherein the water-soluble pre-reacted binder comprises the reaction product(s) of at least one carbohydrate component and at least one first amine component, wherein the ratio of the reactive nitrogen-containing groups of the at least one first amine component to the carbonyl groups of the at least one carbohydrate component is substoichiometric such that there is no full conversion of the at least one carbohydrate component, and
- wherein the at least one second amine component comprises a substituted or unsubstituted primary diamine and/or a substituted or unsubstituted primary triamine.
