Linseed Oil Raw
Linseed Oil Raw is the unrefined, natural oil extracted from flax seeds through cold pressing or solvent extraction. It contains natural impurities such as gums, waxes, and free fatty acids, giving it a darker color and stronger odor compared to refined oils. Raw linseed oil is a drying oil known for its excellent film-forming and adhesive properties. It is widely used in traditional wood finishing, oil painting, and industrial applications where natural and slow-drying oil is preferred.
