SEMITI INK-1 vs Chemours Ti-Pure R-931
SEMITI INK-1 matches Ti-Pure R-931 as an easy-dispersion ink-grade rutile for offset, flexo, gravure, and UV inks.
Ti-Pure R-931 is the global reference ink-grade rutile — engineered for fast bead-mill dispersion, anti-screen-blinding behavior, and tight color spec for high-volume ink production. SEMITI INK-1 is the direct functional alternative.
