GENERAL INFORMATION - Tung Oil
Tung Oil is pressed from the nuts of Tung tree is known also as
China wood oil and nut oil.
Major producing countries are mainland China (Guizhou, Guangxi , Sichuan , Hubei, Hunan, Yunnan, Shaanxi, Jiangxi, Henan ) and South America (Argentina and Paraguay), United States and Africa . Tung tree
farms in the southern U. S. and Argentina now supply tung oil, formerly available only from China. The oil is still known in some circles as "China wood oil".
Tung oil is
an ideal "binder" or "vehicle", carrying the resins and driers deep into the pores of the wood so that sealer and finish coats practically become part of the wood - drying into an
armor-like yet beautiful surface.
Tung oil tree (Aleurites fordii), a deciduous shade tree native to China. It belongs to the Euphorbia Family (Euphorbiaceae) along with the candlenut tree (A
molucanna), another species with seeds rich in unsaturated oils. For centuries tung oil has been used for paints and waterproof coatings, and as a component of caulk and mortar. It is an ingredient in
ink and is commonly used for a lustrous finish on wood. Some woodworkers consider tung oil to be one of the best natural finishes for wood.

Other unsaturated plant oils, such as castor oil and linseed oil, take longer to dry and leave an oily residue until they
soak into the wood surface. Tung oil 's ability to dry quickly and polymerize into a tough, glossy, waterproof coating has made it especially valuable in paints, varnishes, linoleum, oilcloth and
printing inks.
Drupaceous fruit and seeds of the tung oil tree. The oil-rich seeds are produced inside a thick, woody endocarp layer and are the source of tung oil used on fine furniture.

mesocarp and a thin outer skin or exocarp. Fruits with an endocarp layer surrounding the seed are called drupes or drupaceous. The endocarp protects and aids in the dispersal of the vulnerable seed,
especially when it is swallowed by a hungry herbivore. Tung oil is composed primarily of eleostearic (elaeostearic) acid, with smaller amounts of oleic, linoleic and palmitic glycerides.
Eleostearic acid is a crystalline unsaturated fatty acid that exists in 2 stereoisomeric forms: An alpha acid occurring as the glycerol ester especially in tung oil, and a beta acid obtained from the
alpha acid by irradiation. The chemical structure of tung oil eleostearic acid
The largest application for the oil is paint and varnish , and also wide utilized by soap ,inks, electrical insulators,
furniture, shipbuilding, etc. For 600 years the Chinese have treated boat timbers with tung oil.
For 600 years the Chinese have treated boat timbers with tung oil. Tung oil, was used to waterproof
Chinese ships as long ago as the 14th century. The thin, transparent oil penetrates deep into wood pores, forming an almost permanent seal against moisture because it never loses its elasticity.
Tung Oil is the world's oldest and best wood preservative. It was grown in China for many centuries before its introduction into Europe and the America, where it is now grown most notably
in America.
We recommend Tung Oil instead of linseed oil, varnish, lacquer or shellac preparations for the following reasons:
Tung Oil is easy to work with and protects by penetrating the
wood surface, leaving no streaking or brush marks. Tung Oil offers a protective barrier against water, stains, abrasions and wear. Tung Oil will not darken with age, as other finishes will.
Tung
Oil will not mildew - linseed oil will. Linseed oil "bleeds" out too excessively for a satisfactory finish. Tung Oil Finish dries clear to allow the wood's natural beauty to come through.
The look is natural, hand-rubbed, classic; perfect for fine furniture.
The largest application for the oil is paint and varnish, and also wide utilized by soap, inks, electrical insulators.
