Pure Tung Oil is obtained from the seeds of a tropical tree, the Tung tree (Aleurites fordii). It is a member of the spurge Family, and can also be known as China Wood Oil or Nut Oil. The seeds found in the centre of the tung fruit contain more than 50% Tung Oil, which is available when the seeds are ground and pressed. The oil is amber coloured, and contains a high proportion of eleostearic acid. Tung Oil is one of the world's oldest and best natural wood preservers.
For over 600 years, the Chinese have used Tung Oil to waterproof marine timbers. The oil penetrates deeply into most porous surfaces, forming an almost permanent seal against moisture, because it never loses its elasticity.
Tung Oil is non-toxic, food safe and the VOC (volatile organic compound) emission is Zero.
Uses: Can be used as a timber finish and is widely used as a drier in varnishes and paints. Pure Tung Oil is also a most effective seal for concrete bench-tops, floors, slate/ stone, terracotta, mud brick (adobe) and other similar construction materials.
