Common questions about Coloured Rutile TiO2 in pigments applications
C-TOX H (Buff) and G-TOX H (Grey) are engineered rutile TiO₂-bearing pigment extenders derived from ilmenite (FeTiO₃). They act as optical spacers between colour pigment particles, reducing pigment–pigment contact, suppressing agglomeration, improving dispersion stability, and simultaneously providing a controlled buff or grey tonal contribution.
Their dual action — pigment spacing plus controlled tonal contribution — allows partial replacement of expensive white TiO₂ (used as spacer pigment) and costly organic/inorganic colour pigments, maintaining colour performance while significantly reducing formulation cost.
Buff/earth-tone shades (controlled shade development with TiO₂ reduction), grey systems (consistent tint strength and batch reproducibility), muted colours (improved dispersion and tone stability), and cost-sensitive shades (effective pigment replacement without visual compromise).
Yes, both series offer excellent weather resistance, high resistance to acids, alkalis, and chemicals, thermal and UV stability, and are non-toxic and chemically inert — making them reliable for long-term paste storage and downstream application.
Typical loading is 10–50% of the total pigment/extender mix depending on the target shade, TiO₂ replacement level, and desired tint strength. Trials are recommended to optimise performance for each specific pigment system.
