Abstract
Disclosed is a method for stabilisation, hydrophobation and enhanced durability treatment of a ligno-cellulosic material. The method includes the steps of applying a cross-linking formulation including at least one cross-linking acid and at least one polyol, and hydophobation emulsion to a ligno-cellulosic material. The chemically treated material is then subjected to a temperature initiating an esterification reaction between the cross-linking acid, the hydroxyl groups of the cellulose and the polyol. Also disclosed is a bio-based material obtainable by the method.
