Pre-painted steel/aluminum coil producer procurement
TiO2 for Coil Coating Producers
Coil coatings demand 15–25 year outdoor durability. SEMITI 826D is the workhorse — Tronox CR-826 equivalent.
Typical volume
300–2000 t/year per coil coater
Qualification cycle
12–20 weeks (extended weathering required)
Business context
Coil coating producers — Centria, Steelscape, BlueScope, NS BlueScope — paint metal coil continuously for downstream fabrication into roofing, siding, garage doors, appliances. The coated coil is sold with 15–30 year warranties. TiO2 in the topcoat must support that durability.
Procurement challenges
- 0120+ year warranty durability requires premium TiO2 + binder + UV stabilizer system
- 02Pickling and oxidation resistance during coil heating
- 03PVDF / Kynar 500 system compatibility
- 04Color match for architectural cladding consistency
What SEMITI brings
SEMITI 826D for premium coil coating applications. Validated against Tronox CR-826 in coil-coating customer trials. Compatible with PVDF, silicone-polyester, and polyester coil systems.
