Abstract: The present invention relates to a liquid lignin mixture comprising 3-50 wt % methanol, 12-50 wt % lignin and 5-85 wt % aqueous alkali solution wherein the concentration of said aqueous alkali solution is 1 to 50 wt % of alkali in water, based on the weight of said alkali solution prior to mixing with the other components of the mixture. The liquid lignin mixture can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.

Abstract: The present invention relates to a bonding resin useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiber-boards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards. The bonding resin is also useful for example in composites, molding compounds and foundry applications. The invention also relates to a method for preparing the bonding resin. The bonding resin comprises hydroxymethylfurfural, furfural, furfuryl alcohol, acetoxymethyl furfural or oligomer of hydroxymethylfurfural or a combination thereof and one or more crosslinker and optionally one or more additives.
