Rutile Titanium Dioxide R868
Jinan Yuxing R868 Zr/Al-treated rutile titanium dioxide for high-performance coatings, with authorized information and inquiry coordination through TiO2 Source.
R868 is the Jinan Yuxing starting grade for high-performance coatings.
The manufacturer TDS positions R868 for high-performance coatings and describes Zr/Al inorganic coating plus organic treatment. It specifies TiO2 purity of at least 93%, oil absorption no more than 19 g/100 g and pH 7.0-8.8. Exterior weatherability, gloss retention and formulation compatibility still require buyer trials.
R868 manufacturer TDS data.
These values are specification limits from the supplied Jinan Yuxing TDS, not batch results. The current controlled TDS, agreed sales specification and lot COA govern acceptance.
| Parameter | Manufacturer specification | Buyer action |
|---|---|---|
| TiO2 content | >=93% | Confirm the controlled TDS and agreed test method. |
| Rutile conversion | >=97.5% | Retain in the approved purchasing specification if required. |
| 105 C volatile matter | <=0.8% | Confirm method and storage or handling controls. |
| Water-soluble matter / hydrotrope (TDS wording) | <=0.5% | Confirm the controlled TDS wording and analytical method. |
| Sieve residue, 45 micrometres | <=0.05% | Pair with the buyer's fineness-of-grind or dispersion test. |
| Tinting strength vs standard | >=112% | Do not compare directly with R838 Reynolds-number data. |
| pH, aqueous suspension | 7.0-8.8 | Check compatibility with binder, dispersant and additives. |
| Oil absorption | <=19 g/100 g | Evaluate viscosity and dispersant demand in the actual coating. |
| Water-extract resistivity | >=50 ohm m | Confirm units and method on the current TDS. |
| ZrO2 | 0.3-0.6% | Keep the treatment range linked to the named producer and grade. |
| Al2O3 | 3.2-4.0% | Keep the treatment range linked to the named producer and grade. |
| Average particle diameter | 0.20-0.26 micrometres | Use as a TDS descriptor; application dispersion still requires a trial. |
Document boundary: the supplier source PDF is not published as a public download. Request the current controlled TDS with the quotation and approve the commercial lot against its COA.
Where R868 is a documented starting grade.
Manufacturer-listed applications define the starting scope. Final suitability depends on the buyer's formulation, process and acceptance tests.
High-performance coatings
This is the application explicitly stated in the manufacturer TDS. Approve hiding, gloss, viscosity, dispersion and durability in the buyer's resin and additive package.
Exterior coating trials
R868 is the evidence-supported starting grade for demanding coating trials, but the TDS alone does not establish a warranty. Use accelerated and natural exposure criteria appropriate to the end market.
Industrial coatings
Evaluate compatibility with the selected binder, solvent or waterborne system, dispersant and production equipment before approval.
Equivalent-grade projects
Compare the incumbent producer, surface treatment, test methods, COA and retained sample before proposing a controlled R868 trial.
R868 buyer qualification checklist
- Fix Jinan Yuxing R868 and the Zr/Al plus organic treatment declaration on the RFQ.
- Approve the current controlled TDS and SDS.
- Define gloss, hiding, viscosity, colour and durability acceptance tests.
- Run a controlled formulation and weatherability trial against the incumbent.
- Confirm lot COA, retained sample, inspection, packaging and export documents.
Manufacturer and transaction roles
Jinan Yuxing Chemical Co., Ltd., registered in China, manufactures R868. TiO2 Source is the website name used for authorized product information and inquiry coordination. The contractual seller and exporter of record are identified in the quotation, sales contract and shipping documents for each transaction.
R868 sample COA test results.
Historical 2023 Jinan Yuxing COAs record TiO₂ 94.0%, pH 7.5, oil absorption 19 g/100 g, moisture/volatile matter of 0.3–0.5%, and 45 μm residue of 0.02%. Two older documents use the label R93; in this evidence set, R93 corresponds to R868. These are measured historical results only. The specification ranges on this page come from the current controlled TDS, while the agreed specification and commercial lot COA govern acceptance.

R868 sourcing questions.
Who manufactures R868 titanium dioxide?
Jinan Yuxing Chemical manufactures the R868 presented on this site. TiO2 Source coordinates product information and inquiries; the contractual seller and exporter are confirmed for each transaction.
What is the documented application for R868?
The supplied manufacturer TDS states high-performance coatings. Exterior or warranty claims must still be qualified in the buyer's formulation and exposure protocol.
What surface treatment does R868 use?
The manufacturer TDS states inorganic zirconia and alumina treatment plus organic surface treatment, with ZrO2 at 0.3-0.6% and Al2O3 at 3.2-4.0%.
Is R868 automatically suitable for every exterior paint?
No. Resin chemistry, dispersant, pigment volume concentration, additives, substrate and exposure all matter. Approve the grade through formulation and weathering trials.
Are the R868 TDS and COA publicly downloadable?
No supplier source PDF is publicly downloadable here. The current controlled TDS is available with a quotation, and each commercial lot ships with a COA against the agreed specification.
