Rutile TiO2 for high-hiding coatings: field notes, specs, and buyer tips

If you’ve been hunting for a reliable 13463-67-7 titanium dioxide using for coating supplier, the DongFang R5566 keeps popping up in my inbox—usually from paint makers wanting a clean, bright rutile with minimal fuss at the millbase. Originating from Jindi Industrial Park, Dacheng County, Langfang, Hebei, this grade is alumina/zirconia plus an organic treatment. In plain English: easy to disperse, stays white, and holds gloss.

The product name is a mouthful—TiO2 DongFang R5566 Rutile Pigment Hot Seller Titanium Dioxide—but the behavior is familiar: high scattering power, high whiteness, and durability that survives outdoor cycles better than basic grades. Many customers say it “just wets in,” which, to be honest, is what busy dispersion rooms need.

Typical specifications (real-world use may vary)

Process flow, testing, and service life

Feedstocks are rutile or ilmenite, processed by established chloride/sulfate routes, then coated with Al2O3/ZrO2 and an organic finish to enhance wetting and weathering. QC typically follows ISO 591 and ASTM D476 classifications, with gloss checked at 60° (ISO 2813), color by ISO 7724, and accelerated weathering via ASTM G154 QUV. In outdoor acrylic systems, I’ve seen service life around 8–12 years; industrial alkyds, roughly 5–8; marine topcoats can be lower unless you pair it with robust binders and UV package. Your resin system is half the story.

Where it fits

• Architectural exterior and interior wall paints (high hiding, clean tone)
• Industrial primers and topcoats, including alkyd, epoxy, polyurethane
• Coil and can coatings needing gloss retention
• Pigment pastes for tinting systems—thanks to dispersibility

Comparison is approximate, based on public datasheets and field feedback; always validate in your binder system.

Customization, packaging, and real-world feedback

Custom tint strength targets, moisture caps, and grind curves can be discussed—especially if you’re running high-speed dispersers with limited residence time. Common pack: 25 kg bags or FIBC. Actually, one Southeast Asian exterior brand told me they trimmed TiO2 loading by ≈5% versus their previous grade due to stronger tint strength, while holding ΔE under 1.0 after 500h QUV in acrylic—impressive for the price band.

Compliance and documentation

Supplier provides standard QC COAs; ISO 9001/14001, and REACH/RoHS statements are typically available on request. For regulated markets, align with ISO 591 categories and ASTM D476 type definitions. If you need migration or VOC data for specific eco-labels, ask early—lead times happen.

Need samples, TDS, or a millbase check? Ask for a drawdown against your control tint paste. And yes, mention 13463-67-7 titanium dioxide using for coating supplier so the team knows which spec you’re after.
