FAQ

What is Tung oil (CAS: 8001-20-5)?

Tung oil is a natural oil extracted from the seeds of the tung tree (Aleurites fordii), commonly used as a drying oil. Its chemical formula is a complex mixture of unsaturated triglycerides, primarily containing linoleic acid and oleic acid. It exhibits high viscosity, slow drying time, and forms a hard, water-resistant film when polymerized. Tung oil is widely recognized for its chemical stability and traditional applications in coatings and wood finishes.

What are the main uses of Tung oil (CAS: 8001-20-5)?

Tung oil is primarily used in woodworking for creating durable, water-resistant finishes. It also serves as a base in pharmaceuticals for topical medications, an emulsifier in food products, and a component in industrial coatings and adhesives. In research, it is utilized for testing material properties and as a solvent. Its versatility makes it a key ingredient in various applications, including traditional lacquers and modern polymer formulations.

Is Tung oil (CAS: 8001-20-5) safe?

Tung oil is generally safe when used as directed, but proper handling is essential. It may cause skin irritation or respiratory issues if inhaled in large quantities. Safety standards recommend using gloves, ensuring adequate ventilation, and avoiding contact with eyes. While non-toxic in normal use, ingestion should be avoided, and safety data sheets (SDS) should be consulted for detailed precautions.

How should Tung oil (CAS: 8001-20-5) be stored?

Tung oil should be stored in a cool, dark place with temperatures below 25°C to maintain stability. It is sensitive to light and air, so airtight containers and minimal exposure are necessary. Humidity levels should be controlled to prevent degradation, and storage areas should be well-ventilated. Proper storage ensures longevity and preserves its chemical properties for industrial and commercial use.
