Chloride vs Sulfate Rutile Titanium Dioxide

A current-TDS selection guide supporting the rutile titanium dioxide for coatings application page.

Quick Answer: Production process is a useful classification, but it does not determine the correct grade by itself. The current range contains chloride-process and sulfate-process grades with different end uses and surface treatments. M-2377 does not state a process in its current TDS, while high-purity CR-901 uses vapor-phase oxidation. Always return to grade-specific TDS data and application trials.

    M-996: General Coatings Grade; M-2196: Durable Coatings Grade; M-108: High-Thermal-Stability Plastics Grade; M-52: Ink Grade

  • Process not stated in current TDS

    M-2377

    M-2377: Plastics & Rubber Grade

  • Vapor-phase oxidation specialty grade

    CR-901

    CR-901: High-Purity Rutile Grade

Selection Workflow

  1. Step 1: Identify the target application and required end-use performance.
  2. Step 2: Use process as a first classification, not as a quality ranking.
  3. Step 3: Compare surface treatment and only the technical properties stated in each grade TDS.
  4. Step 4: Do not infer a process when the current TDS does not state one.
  5. Step 5: Confirm the shortlist in the buyer’s formulation and processing conditions.

Buyer FAQ

Is chloride-process rutile titanium dioxide always better than sulfate-process?

No. Process is not a universal quality ranking. Grade fit depends on the target application, surface treatment, technical properties, formulation compatibility, and trial results.

What should I do when a process or technical property is not stated?

Treat it as not stated. Do not infer a process, value, approval, or performance claim from another grade or from a general product family.

How can I request the current technical data sheet?

Use the grade-specific TDS links in the comparison table. The selected current document is provided by email after request.
