Tung Oil (Heat-Bodied) for Offset Ink
CAS Number: 8001-20-5
Heat-bodied tung oil is produced by thermal polymerization of raw tung oil to elevated viscosity grades (Z3–Z6), providing a fast-drying, high-gloss vehicle component for premium sheetfed offset and letterpress inks. Its exceptionally high alpha-eleostearic acid content delivers the fastest oxidative drying of any natural oil, producing hard, scratch-resistant ink films with outstanding gloss on coated papers.
