SEMITI 826D vs Tronox CR-826

SEMITI 826D matches Tronox CR-826's industry-leading chalking resistance for coil coatings and outdoor industrial paint.

Tronox CR-826 is the global reference for high-durability outdoor coatings — particularly coil-coated cladding (PVDF, polyester), heavy-duty industrial topcoats, and premium architectural facade systems. SEMITI 826D is the direct functional alternative, with matched heavy alumina + silica + organic surface treatment architecture.

When to choose which

Choose
SEMITI 826D
  • →Coil-coated cladding production in Asia
  • →Heavy-duty industrial topcoats for steel structures, machinery
  • →Premium architectural facade systems
  • →Bridge / infrastructure protective coatings
Choose
Tronox CR-826
  • →Existing Tronox supplier relationship with no cost pressure
  • →Premium consumer or branded cladding where Tronox brand has marketing value

Drop-in substitution

Substitution typically validated by 2000 hr QUV-A panel + standard salt spray. Confirm on PVDF / polyester systems specifically — surface treatment compatibility is the key qualification gate.

Pricing context

Tronox CR-826 lands in Asia at USD 3.80–4.20/kg. SEMITI 826D lands at USD 2.50–2.90/kg.

Bottom line

For Asia-Pacific coil coating and industrial customers, SEMITI 826D is the cost-optimal choice with technically equivalent durability profile.

Common questions

Is SEMITI 826D qualified for PVDF coil coating systems?+
Yes. PVDF systems (Kynar 500, Hylar 5000) require chloride rutile with heavy alumina + silica overcoat. SEMITI 826D meets all major PVDF coil coating specs. We've supported customers through qualification for architectural aluminum cladding and steel roofing applications.
How does SEMITI 826D pricing compare to Tronox CR-826?+
SEMITI 826D is typically 35–45% lower landed cost in Asia and the Middle East — landing at USD 2.50–2.90/kg vs Tronox CR-826 at USD 3.80–4.20/kg. The gap narrows in Europe due to freight. CR-826 carries Tronox's technical support and global qualification network — worthwhile for OEM specs that name CR-826 by brand.
What's the chalking resistance difference between SEMITI 826D and standard chloride rutile?+
Standard chloride rutile (like SEMITI 996) will show visible chalking in QUV accelerated weathering at 500–1000 hours. SEMITI 826D with its heavy silica/alumina overcoat typically shows no chalking at 2000+ hours QUV — equivalent to 10+ years Florida natural weathering. This gap is decisive for roofing, cladding, and exposed industrial steel.
