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.

Abstract: The present invention is directed to a process for preparing coating compositions containing up to 100% bio-based content. The coating compositions are used for coating metal, paper and wood substrates in various applications. The process for preparing the coating composition comprises the steps of providing lignin, wherein the lignin is agglomerated and has a particle size distribution such that at least 80 wt-% of the agglomerates have a diameter within the range of from 0.2 mm to 5.0 mm, dissolving the agglomerated lignin in an organic solvent, and mixing the solution with a crosslinker to obtain a coating composition.
