    Abstract: The present invention relates to the use of a bonding resin prepared by providing an aqueous solution comprising at least one biobased product selected from tannin, starch, soy protein, glycerol, chitin, pectin, dextrose or other carbohydrates, or a mixture thereof and mixing the aqueous solution 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 used in the manufacture of laminates, mineral wool insulation or engineered wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF) or particle boards. Preferably, the bonding resin does not comprise lignin.

    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, glycerol triglycidyl ether, sorbitol polyglycidyl ether, ethylene glycol diglycidyl ether, polyethylene glycol diglycidyl ether having 2-9 ethylene glycol units, propylene glycol diglycidyl ether having 1-3 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, laminated veneer lumber (LVL), medium density fiberboards (MDF) , high density fiberboards (HDF) and particle boards.
