Coatings are the biggest single market for titanium dioxide, and the most demanding on pigment quality. Opacity, gloss, whiteness and exterior durability all trace back to the grade you choose and how well it disperses in your binder system.
What the pigment has to deliver
- Hiding power
- Efficient light scattering so the film covers the substrate at the lowest practical pigment loading.
- Gloss development
- Fine, evenly dispersed particles that leave a smooth film surface rather than a hazy one.
- Exterior durability
- Inorganic coatings that suppress photocatalytic activity and prevent chalking and gloss loss.
- Dispersibility
- Short mill times, stable viscosity and no specks or seeds in the finished film.
Matching grade to coating type
Architectural and decorative
Interior and exterior emulsions, primers and trim paints. Cost-efficient sulfate rutile grades with strong whiteness and good dispersibility usually give the best balance.
Industrial, automotive and powder
Coil, powder, OEM and refinish systems need higher gloss, cleaner undertone and long weathering life. Chloride-process grades with tight particle-size control are typically specified.
Printing inks and packaging coatings
Opacity in thin films with good flow. General-purpose grades with a bluish undertone perform well here.

Practical formulating notes
- Check oil absorption before pushing pigment volume concentration upward.
- Confirm the surface treatment suits your binder chemistry — waterborne and solventborne differ.
- Compare on equal hiding, not equal weight, when you benchmark two grades.
- Run an accelerated weathering panel before switching an exterior product.
