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.

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 certain crosslinkers such as ethers, and optionally one or more additives. The bonding resin is used in the manufacture of laminates, mineral wool insulation or wood products, such as 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.
