R-5566 Rutile Titanium Dioxide Pigment with 94.4% TiO2 Content, 99.3% Rutile Content, and 1977 Tinting Strength

R-5566 Rutile Titanium Dioxide - Quality & Technical Report

1. Executive Summary

R-5566 is identified in the supplied Certificate of Analysis (COA) as a rutile titanium dioxide pigment. The inspected batch, No. 23-07-14-02-09, was tested on 16 July 2023, with a stated quantity of 20 metric tons and packaging of 25 kg per bag.

All reported inspection results comply with the technical criteria shown on the COA. The batch was therefore judged qualified under the referenced standard Q/78911824-0.001-2023.

This report expands the batch COA into a customer-facing English technical document. The numerical values below are batch-specific inspection results and should not automatically be interpreted as universal typical values for every R-5566 production lot.

3. Quality Inspection Results

4. Technical Performance Interpretation

TiO2 and rutile content: The batch reports 94.4% TiO2 and 99.3% rutile content, both above the stated acceptance limits. These are important identity and quality-control indicators for a rutile titanium dioxide pigment.

Brightness: The measured brightness of 94.8 exceeds the stated minimum of 94.5, supporting the batch's white-pigment appearance requirement.

Tinting strength: A Reynolds coefficient of 1977 exceeds the minimum requirement of 1900. This indicates conformity with the batch standard for relative tint-reducing performance; the COA does not provide a separate comparative reference pigment or application formulation.

Volatile matter: The result of 0.4% is below the 0.5% maximum and indicates compliance with the stated volatile-matter control at 105 C.

Oil absorption: The measured 16 g/100 g is below the 20 g/100 g maximum. Oil absorption is commonly useful in formulation work as an indicator of liquid/binder demand, although the COA does not provide application-specific viscosity data.

Coarse residue and dispersibility: Residue on the 45 um sieve is 0.01%, while the Hegman dispersibility result is 6.50. Both satisfy the stated requirements and provide batch-level evidence of controlled coarse material and acceptable dispersion quality.

Aqueous characteristics: The pH result is 6.8 within the required 6.0-9.0 range, and aqueous-extract resistivity is 213 ohm.m versus a minimum of 80 ohm.m.

6. Potential Application Relevance

The supplied COA does not list recommended end-use applications. Accordingly, the following points are technical interpretation rather than manufacturer-stated application claims.

7. Quality Control & Incoming Inspection Recommendations

Verify batch number and supplier COA against delivered packaging.

Retain a sealed reference sample from each received lot.

Confirm TiO2 content, brightness, tinting strength, oil absorption and dispersion using agreed methods where these are critical to the customer application.

Use side-by-side application testing against an approved reference pigment before changing commercial formulations.

Treat the reported values in this document as results for batch 23-07-14-02-09 unless the supplier separately confirms grade-wide specifications.

8. Commercial & Technical Evaluation Summary

9. Limitations of the Supplied Data

The source is a batch Certificate of Analysis rather than a full Technical Data Sheet. It does not state the manufacturing process, inorganic/organic surface treatment, recommended applications, durability/weatherability, particle-size distribution, packaging alternatives, storage conditions or safety instructions. This report does not invent those missing product claims.

For commercial qualification, the current manufacturer TDS, SDS, grade specification and lot-specific COA should be reviewed together when available.

10. Conclusion

The supplied COA confirms that R-5566 batch 23-07-14-02-09 met every listed technical requirement and was judged qualified. Particularly notable batch results include TiO2 content of 94.4%, rutile content of 99.3%, tinting strength of 1977, oil absorption of 16 g/100 g, 45 um residue of 0.01% and Hegman dispersibility of 6.50.
