Calcium Carbonate
Ground calcium carbonate, graded for consistent brightness and particle size.
Learn MoreWhite Pigments are engineered composites of titanium dioxide and calcium carbonate that deliver strong opacity while helping reduce TiO₂ use by 10-50%, depending on the application.

The table below shows our six White Pigment grades. Compare the specification and particle size figures to match fineness to your formulation.
| Grade | Type | SiO₂ (%) | Particle size | Refractive Index | D50, microns | Reflectance (R457) | Oil Absorption (/100g) | pH (10% slurry) | Specific Gravity | Applications | Stocked In |
|---|---|---|---|---|---|---|---|---|---|---|---|
| FP440 | powder | 1.85 | 99.0 | n/a | n/a | n/a | n/a | n/a | n/a | Paint & Coatings | DBN & CPT |
| FP550 | powder | 1.85 | 98.8 | n/a | n/a | n/a | n/a | n/a | n/a | Plastics | # |
| X-Pure TiO3 | Core-shell hybrid replacement pigment | n/a | n/a | 2.7 | 0.7 max | >97% | 28 | 9.0 ± 0.5 | 3.53 | Paint & Coatings | DBN & CPT |
| X-Pure TiO4 | Core-shell hybrid replacement pigment, weather-resistant | 2.7 | 0.7 max | >98% | 27 | 7.0 ± 0.5 | 3.52 | Paint & Coatings | DBN & CPT | ||
| X-Paque K-98 | Engineered synthesis crystal platform coated with titanium dioxide | 2 | <0.7 | >96% | 53 | 10.0 ± 0.5 | 2.6 | Paint & Coatings | DBN & CPT | ||
| X-Paque K-99 | Engineered synthesis crystal platform coated with titanium dioxide | 1.8 | ≤ 1.0 | > 98% | 40 | 10.0 ± 0.5 | 2.60 | Paint & Coatings | DBN & CPT |
No grades match this application.
NOTE: # = Not in SA but can be ordered in FCLs (Full Container Loads). X-Paque K-98 is acid-sensitive, not suitable for acid-containing coating systems. X-Pure TiO4 offers enhanced weather resistance, suited to exterior coatings. X-Pure TiO3 is the general-purpose grade of the two.
Unusually close to TiO₂ itself, meaning this extender contributes genuine opacity rather than acting as inert bulk filler.
Lets paint formulators reduce costly TiO₂ loading while maintaining hiding power, a direct cost saving.
Consistent particle distribution (D50=1.1u) supports predictable dispersion and opacity contribution batch to batch.
FP440 suited to Paint & Coatings and FP550 to Plastics, giving formulators both options from the same product family.
