R-5566 and CR-350 are both rutile titanium dioxide grades for coatings, but they come from different production routes and suit different jobs. This is the comparison buyers ask us for most often, so here it is in plain terms.
R-5566 — sulfate process, paint-focused
R-5566 is a sulfate-process rutile grade with an alumina, zirconia and organic surface treatment, developed for paint: interior and exterior architectural systems, emulsions and powder coatings. It offers strong whiteness, reliable dispersibility and a cost-efficient position for high-volume decorative production.
See the R-5566 specification and datasheet
CR-350 — chloride process, all-rounder
CR-350 is a chloride-process rutile grade produced with advanced particle-size control. It gives whiteness with a bluish undertone, efficient dispersibility and high gloss, and it spans building coatings, automotive OEM and refinish, coil and powder coatings, and letterpress, offset and gravure inks.

Side by side
- Process
- R-5566 is sulfate process; CR-350 is chloride process with tighter particle-size control.
- Best fit
- R-5566 for decorative and architectural paint programmes; CR-350 where gloss, undertone and durability are performance-critical.
- Breadth
- R-5566 is paint-focused; CR-350 also covers inks and premium industrial coating systems.
- Commercial position
- Sulfate grades are typically the more economical choice; chloride grades carry a premium for the performance they add.
How to decide
- Define the finish: high-gloss industrial or matte-to-satin decorative?
- Check exposure: interior, or long exterior service life?
- Compare the two datasheets on oil absorption and dispersibility for your system.
- Request both samples and run them side by side on equal hiding.
We will send both samples so you can test them in your own formulation. Send us an enquiry or browse the grade catalogue.
