Micro talc (CAS 14807‑96‑6) supplied by Global Optimals is a high‑purity fine powder containing at least 85 % SiO₂ and over 60 % magnesium oxide, with a particle size distribution of 5–15 µm and moisture content not exceeding 0.5 %. Talc is a layered magnesium silicate that naturally exhibits hydrophobicity and the ability to form a thin, uniform film, making it an effective filler in both water‑borne and solvent‑borne systems. Its crystal lattice scatters light efficiently, delivering a matte appearance without sacrificing brightness, while also enhancing resistance to acidic and alkaline environments. In paint formulations micro‑talc is frequently combined with titanium dioxide, zinc oxide, or polymer dispersions to fine‑tune opacity, improve substrate adhesion, and stabilize pigment suspensions. In acrylic and emulsion paints it acts as a viscosity‑building agent, reducing the need for volatile solvents, and in polyurethane emulsions it serves as a dispersant stabilizer, preventing pigment settling. In sealants, the addition of micro‑talc improves UV stability and reduces shrinkage during cure, and in plastic and rubber compounds it raises impact toughness and lowers friction, which is valuable for automotive gaskets, cable jackets, and molded rubber parts. Recommended dosage in coating batches ranges from 2 % to 10 % of the dry mix, with higher loadings employed in specialty anti‑corrosion or barrier coatings to boost protective performance. Proper handling includes low‑speed, thorough mixing to avoid agglomeration and ensure uniform distribution. For storage, keep the material in a dry, cool environment sealed in polypropylene bags to prevent moisture uptake. During handling, wear protective gloves and a mask because fine particles may irritate the respiratory tract. Global Optimals provides complete documentation (TDS, SDS, COA) and fast delivery from its Tashkent warehouse within 2‑5 business days. Our customers have successfully applied the product in over 500 industrial projects across Uzbekistan, Kazakhstan and Russia.

Micro talc should be stored in a dry, well‑ventilated area at ambient temperatures typical for fine powders (approximately 15‑25 °C), protected from direct sunlight and moisture condensation. When the packaging remains intact, the product’s shelf life is generally 12‑24 months. During handling, wear protective gloves, goggles and a dust mask, and minimize dust generation. Ensure the container is tightly sealed and free of damage to prevent ingress of moisture or contaminants.
