SEMITI 706W vs Chemours Ti-Pure R-746
SEMITI 706W matches Ti-Pure R-746 as a hydrophilic-tuned rutile for waterborne architectural emulsion paints.
Ti-Pure R-746 is Chemours' premium waterborne emulsion paint TiO2 — engineered specifically for maximum hiding-per-kg in waterborne architectural systems. SEMITI 706W is the direct technical equivalent: same hydrophilic-tuned surface treatment, same emphasis on dispersion in waterborne grind, and the same target of 8–12% TiO2 demand reduction vs universal rutile grades.
Side-by-side specification
Typical published specs for the two grades. Customer-specific CoA on inquiry.
| Property | SEMITI 706W | Chemours Ti-Pure R-746 |
|---|---|---|
| Surface treatment | Heavy alumina + hydrophilic organic | Heavy alumina + hydrophilic organic |
| TiO2 demand reduction vs R-902 | 8–12% lower at iso-opacity | 8–12% lower at iso-opacity |
| Tinting strength | ≥1900 | ≥1900 |
| Anti-settling (90-day static) | Pass full redispersion | Pass full redispersion |
| Color (b*) | ≤1.8 | ≤1.7 |
| Landed cost (Asia) | Significantly lower | Reference |
Bold amber indicates the column with the stronger value on that line.
When to choose which
- →Volume waterborne paint production (> 500 t/year) where the demand-reduction savings + cost advantage compound
- →Existing R-746-qualified formulations needing cost-down
- →Premium architectural waterborne lines with TiO2 cost as material margin lever
- →Premium consumer brand where Chemours qualification has marketing weight
- →Very tight color-match in white-on-white tinting
Drop-in substitution
Pricing context
Ti-Pure R-746 commands a premium over R-902 (typically USD 4.20–4.60/kg FCL Asia). SEMITI 706W lands at USD 2.90–3.30/kg — combined cost advantage of ~35% plus the existing demand-reduction.
For waterborne emulsion paint plants > 500 t/year, the math strongly favors SEMITI 706W substitution. Two-stage savings: lower TiO2 demand + lower per-kg cost.
