Premium Tung Oil – A Natural Choice for Industrial Excellence
Tung oil, also known as China wood oil or Vernicia montana oil, is a natural drying oil extracted from the seeds of the Tung tree (Aleurites montana). Native to Asia and widely cultivated across Vietnam, this remarkable oil has become a vital ingredient in various industries due to its high-performance characteristics and environmentally friendly nature.
What Is Tung Oil?
Tung oil is a plant-based oil pressed from the seeds of the Tung tree, sometimes referred to as the “oil paint tree.”The scientific name for the Tung tree is Aleurites montana. It is widely valued for its fast-drying and film-forming properties, making it a superior alternative to synthetic finishes and coatings. Vietnam is one of the primary producers, with an annual capacity of up to 300 tons.
This versatile product is not just used for its coating ability but also for its chemical composition rich in alpha-eleostearic acid, giving it exceptional resistance to moisture, corrosion, and extreme temperatures.

Botanical Characteristics and Growth Conditions
The Tung tree is a robust species reaching heights of 8 meters or more. Its foliage varies in shape—ranging from heart-shaped to deeply lobed—with a smooth trunk and striking red glands at the base of the leaf blades. These trees bloom in April and sometimes again in September, producing white flowers with purple spots. The resulting green, egg-shaped fruits contain oil-rich seeds.
Tung trees thrive in well-drained, cool soils, often found on hilly terrain. In Vietnam, they are commonly grown across provinces such as Ninh Binh, Nam Dinh, Hoa Binh, Nghe An, and Phu Tho, among others. The species is adaptable and often used to shade tea, pineapple, and coffee plantations due to its fast growth and broad canopy.
Production and Yield
Each 100 kilograms of unshelled Tung seeds yields approximately 19–20 kilograms of oil and 60–65 kilograms of oil cake, which contains significant protein and minerals. While the oil cake holds agricultural value, the raw seeds and leaves are toxic due to natural saponins and require detoxification before use in animal feed.

Physical and Chemical Profile
Tung oil presents as a clear yellow liquid with a mild, natural aroma. Its notable physical properties include:
-
Specific Gravity (20°C): 0.920–0.945
-
Refractive Index (20°C): 1.500–1.520
-
Acid Value: 1.4
-
Iodine Value: 149.5–170.58
-
Saponification Value: 193.38–196.73
The key compound, alpha-eleostearic acid, accounts for 70–80% of its fatty acid content. This compound is a polyunsaturated fatty acid with three double bonds, giving the oil its superior oxidizing and drying performance. Once dried, Tung oil forms a flexible, waterproof film that can resist weather, corrosion, and oxidation, making it ideal for demanding applications.

Wide-Ranging Industrial Uses
Thanks to its durability, moisture resistance, and chemical stability, Tung oil is a preferred raw material in the manufacturing of:
-
Heat- and acid-resistant paints
-
Protective coatings for ships, airplanes, and automobiles
-
Electrical insulating and heat-insulating varnishes
-
Printing inks and fine art paints
-
Synthetic rubber and plastics
-
Soaps, oilcloth, linoleum, and artificial leather

Beyond its liquid form, the oil cake is used in fertilizers or as animal feed after detoxification. The fruit husks are repurposed into activated carbon, and the wood—though soft and termite-prone—is suitable for pulp, firewood, or engineered wood products.

Packaging, Storage & Transportation
