In powder coatings, a 1% change in TiO₂ loading may look insignificant.
But when production volumes reach hundreds or thousands of tons, that small percentage can have a surprisingly big impact on your annual raw material cost.
More TiO₂ ≠ Always Better Performance
TiO₂ provides excellent whiteness, opacity and hiding power. However, simply increasing the dosage does not always deliver the same improvement in performance.
At a certain point, the additional TiO₂ may bring limited performance gains while increasing formulation costs.
The Real Question Is: How Much TiO₂ Do You Really Need?
The right TiO₂ level depends on several factors:
1.TiO₂ grade and particle size
2. Dispersion performance
3. Hiding power requirements
4. Resin system
5. Pigment volume concentration
6. Interaction with fillers such as BaSO₄
Sometimes, Optimization Is Better Than Increasing TiO₂
For some powder coating formulations, optimizing the balance between TiO₂ and BaSO₄ can help control raw material costs while maintaining the required whiteness, opacity and coating performance.
The goal isn’t simply to use more TiO₂.
The goal is to find the right TiO₂ at the right dosage for the right formulation.
