Mineral Oil (Naphthenic, Ink Grade)
CAS Number: 64741-89-5
Low-aromatic, naphthenic process oil used as a non-drying diluent and tack modifier in coldset newsprint inks, offset lithographic inks, and letterpress formulations. Ink-grade mineral oil provides controlled penetration into newsprint and uncoated papers, enabling rapid ink setting without oxidative drying mechanisms. Available in a range of viscosities (low, medium, high) to optimize ink flow and print quality.
