Common questions about Engineered Aluminum Silicate in pigments applications
Its platy lamellar particle structure creates effective pigment spacing, reducing agglomeration and improving dispersion uniformity. Advanced cryogenic magnetic purification removes discolouring impurities, delivering higher brightness, improved whiteness, and a lower yellow index for a cleaner optical background in colour-critical pigment systems.
Operated at temperatures down to –260°C, the magnetic system achieves exceptionally high sensitivity, effectively removing magnetic, paramagnetic, and trace iron-bearing mineral impurities — significantly reducing discolouring contaminants and resulting in higher brightness, improved whiteness, and lower yellow index.
The lamellar plate-like structure positions between primary pigment particles, creating effective inter-particle spacing that reduces pigment–pigment contact, minimises agglomeration and flocculation, and improves dispersion uniformity in both water-based and solvent-based paste systems.
Hydrous kaolin (Coating Clay 90, Pearlglan) provides effective pigment spacing, brightness, and optical neutrality. Calcined kaolin (Glazex 90, Hyperglan) adds internal porosity and increased brightness through thermal processing, enhancing dry opacity contribution and TiO₂ spacing efficiency in the pigment system.
Improved pigment utilisation, stable dispersion behaviour, reliable paste stability, reduced formulation variability, consistent optical performance, and enhanced suspension stability in high-solid pigment concentrates.
