BINDER COMPOSITION

A method for producing a binder composition is disclosed. The method may comprise: i) providing a raw material of crushed lignin agglomerates, wherein at least 90 weight-% of the crushed lignin agglomerates have a particle size of at most 10 mm; ii) dissolving the provided raw material into an aqueo...

Summary:A method for producing a binder composition is disclosed. The method may comprise: i) providing a raw material of crushed lignin agglomerates, wherein at least 90 weight-% of the crushed lignin agglomerates have a particle size of at most 10 mm; ii) dissolving the provided raw material into an aqueous solvent composition, wherein at least 95 weight-% of the total amount of the raw material provided into the aqueous solvent composition is dissolved into the aqueous solvent composition within at most 60 minutes; and iii) heating the composition formed in step ii) at a temperature of 60 - 150 °C in the presence of crosslinking agent and compound selected from the class of phenols for polymerizing the raw material, the crosslinking agent, and the compound selected from the class of phenols.
