Development Of New Organic Wood Paints With Lignin As Additive

Lignin has been used as additive in preparation of the new organic paints. Soda lignin was extracted from black liquor of soda-AQ (anthraquinone) pulping of oil palm empty fruit bunch (EFB) fibers by 20% sulfuric acid precipitation. Two different types of azo pigment namely, phenyl-azo-2-naphthol an...
