    Abstract: The present invention relates to adhesive mixtures. In particular, the invention concerns the use of lignin in biobased hot-melt (non-pressure sensitive) and pressure sensitive adhesives, as well as novel adhesive mixtures suitable for use as such adhesives. The adhesive mixture comprises 25-85 wt-% lignin, 10-75 wt-% plasticizer, 0-50 wt-% tackifier and 0-40 wt-% waxes, by solid weight. The combined amount of lignin, plasticizer, tackifier and waxes is at least 90 wt-%, by solid weight, of the adhesive mixture.

    Abstract: The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of an aqueous solution and mixed with one or more of glycerol diglycidyl ether, polyglycerol diglycidyl ether, polyglycerol polyglycidyl ether, glycerol triglycidyl ether, sorbitol polyglycidyl ether, alkoxylated glycerol polyglycidyl ether, trimethylolpropane triglycidyl ether, trimethylolpropane diglycidyl ether, polyoxypropylene glycol diglycidylether, polyoxypropylene glycol triglycidyl ether, diglycidylether of cyclohexane dimethanol, resorcinol diglycidyl ether, isosorbide diglycidyl ether, pentaerythritol tetraglycidyl ether, ethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether having 2-9 ethylene glycol units, propylene glycol diglycidyl ether having 1-5 propylene glycol units, and/or diglycidyl ether of terminal diol having a linear carbon chain of 3-6 carbon atoms; and optionally one or more additives. 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.
