Description

Tung Oil Fatty Acid is a mixture of unsaturated fatty acids derived from the hydrolysis of tung oil. This specialized chemical is valued for its unique conjugated triene structure, which imparts excellent drying and cross-linking properties. It serves as a critical raw material for manufacturers in the coatings, resins, and polymer industries seeking to enhance product durability and performance.

Application

• Alkyd Resins & Drying Oils: A key component for formulating high-performance, fast-drying alkyd resins used in industrial and protective coatings.
• Polymer & Plastic Additives: Used as a modifier and cross-linking agent to improve the flexibility and weathering resistance of various polymers.
• Corrosion Inhibitors: Employed in the formulation of rust-preventative coatings and lubricant additives.
• Surfactants & Intermediate Synthesis: Acts as a bio-based feedstock for producing specialized surfactants and other chemical intermediates.
• Inks & Varnishes: Enhances the drying speed, gloss, and hardness of printing inks and wood varnishes.
• Adhesives & Sealants: Incorporated to improve the adhesive strength and water resistance of various bonding compounds.

Quality Control

Our Tung Oil Fatty Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as acid value, iodine value, and fatty acid composition. Our commitment to quality supports compliance with relevant industry standards for raw material sourcing and manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and oxidizing agents. Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen blanket) for long-term preservation to maintain optimal quality and prevent polymerization. Recommended storage temperature is 15-25°C.
