Mineral Engineered Benefits
Rio Clays' high-purity minerals are engineered to optimize performance across architectural and industrial coating systems.
Opacity & Hiding
Optimized particle size distribution enhances light scattering, allowing for TiO2 extension and improved dry hide in decorative paints.
Brightness & Gloss
Engineered kaolin provides high whiteness and controlled matting effects, ensuring consistent sheen levels and vibrant color development.
Tint Strength
Superior mineral dispersion ensures maximum pigment efficiency and uniform tinting strength across large production batches.
Viscosity Control
Our plate-like kaolin structure aids in rheology modification, preventing settling and improving sag resistance during application.
