Abstract: The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of a solution in ammonia and/or an organic base and mixed with one or more crosslinkers 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. The bonding resin is also useful for example in composites, molding compounds and foundry applications.
