Talc is a hydrated magnesium silicate mineral distinguished by its lamellar (platy) crystal structure and exceptionally low Mohs hardness of 1, making it the softest known mineral. Its surfaces are intrinsically hydrophobic due to electrically neutral silic...

Common questions about Precipitated & Fumed Silica in pigments applications
Talc's platy lamellar structure aligns between pigment grains creating controlled spacing that reduces pigment–pigment contact, improves packing efficiency, and enhances dispersion uniformity. Its low hardness (Mohs ~1) ensures minimal mechanical stress during processing, and chemical inertness prevents interference with pigment chemistry.
Talc surfaces are intrinsically hydrophobic due to electrically neutral silicate layers — this allows talc particles to resist moisture interaction, maintain stable dispersion behaviour, and prevent water-induced agglomeration in pigment paste formulations.
Due to its low hardness and hydrophobic nature, talc supports pigment suspension, prevents rapid settling, and helps maintain controlled viscosity — critical for handling, storage, and processing stability of high-solid pigment concentrates.
Micron Talc G-Flex is an engineered lamellar grade optimised for organic pigment pastes in both water-based and solvent-based systems. AR Talc is a high aspect ratio grade for premium applications requiring maximum pigment spacing efficiency and superior suspension stability in high-load concentrates.
Improved dispersion stability, consistent optical performance, enhanced handling and storage stability, reduced formulation variability, and reliable pigment system performance across organic and inorganic pigment applications.
