High brightness (ISO brightness >92%) for superior whiteness in demanding coating and pigment applications.
Optimized particle size distribution with narrow D50 (~0.7 µm) ensuring excellent dispersion and smooth film formation.
Enhanced chemical inertness due to complete calcination, providing stability in alkaline and acidic systems.
Low oil absorption (~58 g/100g) enabling high solids loading and improved rheology control in coatings and plastics.
Consistent batch-to-batch quality supported by Imerys’ global manufacturing standards and rigorous QC protocols.
High-performance paper coating pigments for premium LWC and SC papers.
Functional extender in water-based architectural and industrial coatings.
Reinforcing filler in engineering thermoplastics, including polypropylene and ABS compounds.
Pigment-grade additive in specialty inks requiring high gloss and opacity.
Performance-enhancing component in high-end adhesives and sealants.
