DOGUIDE SR-2400

1. Executive Summary

DOGUIDE SR-2400 is a rutile titanium dioxide (TiO₂) pigment with inorganic silicon/aluminum surface coating and organic treatment. The manufacturer describes it as having high whiteness, tinting strength, durability and dispersion. It is positioned for rigid PVC, exterior plastics, rubber and powder coatings.

The original technical data sheet also mentions SR-2400+, an upgraded version using optimized high-temperature dense silica coating technology. The SR-2400+ performance narrative is not a separate specification for SR-2400; no independent SR-2400+ numerical property table is supplied.

3. Manufacturer Technical Specifications

4. Technical Performance Interpretation

Pigment chemistry: The high rutile fraction and TiO₂ content identify the grade as a rutile titanium dioxide pigment. Optical performance depends on dispersion, loading and the host formulation.

Whiteness and lightness: Whiteness ≥97.0% and L value ≥98 are source-stated powder appearance criteria. Finished-product color must be verified under the relevant application test method.

Tinting strength: Tint reducing power ≥180% indicates the manufacturer’s relative tinting-performance criterion; the source does not define the reference standard or full test procedure.

Surface treatment: Si/Al inorganic coating and organic treatment are stated. These treatments are intended to support dispersion and durability, but performance should be validated in each formulation.

Oil absorption: 18–21 g/100 g is a formulation-relevant parameter. It is not a universal predictor of polymer melt rheology or coating viscosity.

Residue and solubles: Low sieve residue and water-soluble content support batch cleanliness and impurity control.

Electrical resistivity: The ≥8500 Ω·cm value is a source-defined quality parameter; the specific test conditions are not supplied.

Ambiguous pH entry: The pH row contains hydrophobic/half-hydrophobic descriptors instead of a numeric pH. This is preserved as printed and requires manufacturer clarification.

5. Application Assessment

6. Formulation and Processing Recommendations

• Begin with controlled laboratory trials in the actual polymer, rubber or coating binder system.
• Benchmark dispersion, whiteness, tinting strength and surface appearance against the incumbent pigment at equal loading.
• For exterior plastics and powder coatings, assess accelerated weathering and field performance; the source does not provide numeric weathering test results.
• Check formulation rheology, processing temperatures, thermal color and final-product properties in production-representative conditions.
• Request the manufacturer’s current COA and full test methods before converting these technical-sheet values into contractual acceptance criteria.

9. Classification, Packaging and Handling

The sheet lists ISO 591-1:2000(E) classification R2 and ASTM D476-00 classification II. Packaging options are 25 kg full-paper bags and 500 kg or 1000 kg PP woven bags. No detailed storage, shelf-life or hazard classification is supplied; consult the current manufacturer SDS and packaging instructions. General good practice includes dry, clean storage and minimizing dust generation.

10. Data Limitations and Conclusion

The supplied one-page TDS does not provide independent weathering test results, complete test methods, particle-size distribution, numerical pH, application-specific dosage or finished-product performance guarantees. The ambiguous slurry-pH row should be clarified with the supplier. Application guidance in this report is technical interpretation, not an additional manufacturer specification.

SR-2400 is a Si/Al-treated rutile titanium dioxide pigment positioned for rigid PVC, exterior plastics, rubber and powder coatings. Its documented whiteness, tinting strength, rutile content, residue control and oil absorption make it a candidate for application trials. Final selection should be based on supplier documentation, COA verification and comparative performance testing.
