What is Tung oil

**Introduction to Tung Oil** Tung oil, derived from the seeds of the tung tree (*Vernicia fordii*), is a natural drying oil renowned for its water-resistant and durable finish. Used for centuries in woodworking, it penetrates deep into surfaces, enhancing grain patterns while providing a protective, lustrous sheen. Unlike synthetic alternatives, tung oil is eco-friendly and non-toxic when pure, making it ideal for food-safe applications like cutting boards and furniture. It dries to a hard, flexible film that resists moisture, mildew, and wear, ensuring long-lasting protection. Popular among craftsmen and DIY enthusiasts, tung oil is valued for its versatility, enhancing both indoor and outdoor projects with a warm, natural aesthetic.

Preparation Process: Tung oil is prepared by extracting oil from the seeds of the tung tree (*Vernicia fordii*). The process involves harvesting ripe seeds, drying them, and mechanically pressing or solvent-extracting the oil. The crude oil is then refined to remove impurities through filtration, degumming (removing phospholipids), neutralization (reducing free fatty acids), bleaching (adsorbing pigments), and deodorization (removing volatile compounds). Alternatively, raw tung oil can be heat-treated (polymerized) to improve drying properties. The final product is a pale yellow to dark brown viscous liquid, rich in eleostearic acid, used as a drying oil in paints, varnishes, and wood finishes.

Usage Scenarios: Tung oil, derived from the seeds of the tung tree, is primarily used as a natural, durable wood finish. It penetrates deeply, enhancing grain and providing a water-resistant, glossy, or matte finish depending on application. Ideal for furniture, flooring, and wooden utensils, it offers protection against moisture, mold, and mild acids. Tung oil dries slowly, forming a flexible, non-toxic coating resistant to wear and heat. It is favored in fine woodworking and restoration for its eco-friendly, non-yellowing properties. Additionally, it serves as a binder in paints, varnishes, and linoleum, and is used in traditional Chinese waterproofing for boats and paper umbrellas.
