TALCUM POWDER FOR COATING INDUSTRY
Molecular formula: H2Mg3O12Si4HS code: 25262020
CAS No.: 14807-96-6
EINECS No: 238-877-9
Talc is Hydrated Magnesium Silicate, it is a versatile material, also known as steatite or soapstone.
Talc is platy structure, it represents a good modifier for elastomers enhancing rigidity and barrier properties.
Talc powder has high specific surface, talc also works as dusting/partitioning agent for sticky compounds, improving handling and preventing agglomeration.

Talc lubricity and anti-sticking, flow, fire resistance, acid resistance, insulation, high melting point, chemically inactive, good covering, soft, good gloss, strong adhesive, excellent physical and chemical properties, because of the layered structure of talc, so it is easy to split into flake trends and special lubrication if high Fe2O3 content will reduce its insulation.
Talc make ideal multi-functional pigments, fillers and extenders in water borne, solvent borne and powder-coat based architectural and industrial paints, where they improve mechanical properties, optical properties and production processes. They also bring benefits to color concentrates, enamels, varnishes, gel coats inks, putties, body fillers, mortars and asphalts.
Talc are proven anti-corrosion, hydrophobic mineral pigments, limiting the penetration of water and corrosive agents into the paint film and reducing corrosion, caulking, peeling and blistering. Due to its lamellarity and chemical inertness, talc also promotes adhesion increasing the paint's durability.
Factory standard: 25kg/bag, plastic woven bag with lining.
