    Abstract: The present invention relates to a process for preparing a bonding resin, lignin in solid form or in the form of a dispersion in water is mixed with a crosslinker; and optionally one or more additives followed by addition of a basic solution. The bonding resin is 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 fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards, laminates or mineral wool insulation.

    Abstract: The present invention relates to a liquid lignin mixture comprising 3-50 wt% methanol, 12-50 wt% ligninand5-85 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 an adhesive formulation comprising lignin, suitable for use in the manufacture of for example wood products.The lignin is provided in the form of a solution or dispersion or in dry solid form, such as in the form of a powder. The adhesive formulation also comprises phenol- formaldehyde (PF) resin and/or lignin-phenol-formaldehyde (LPF) resin. The adhesive formulation may also comprise extenders, hardeners, fillers and other additives, to achieve an adhesive formulation useful in the manufacture of for example wood products, such as plywood and laminated veneer lumber (LVL).The adhesive formulation can also be used in the manufacture of laminates and oriented strand boards.
