Testing IndicatorsAppearance — Visual inspection; Particle size distribution — Laser diffraction analysis; Chemical composition — XRF or ICP-OES analysis; Moisture content — Loss on drying (LOD); Mineral phase identification — X-ray diffraction (XRD); Specific surface area — BET nitrogen adsorption method; pH value — Aqueous dispersion pH measurement; Rheological properties — Brookfield viscosity or rotational rheometer testing; Heavy metals — ICP-MS/ICP-OES.
Storage NotesStore in a cool, dry, and well-ventilated area. Keep container tightly sealed to prevent moisture absorption and contamination. Avoid direct sunlight and high humidity. Store away from strong acids and reactive chemicals. Handle carefully to prevent powder dispersion.
Lead Time10 days
Laponite CP is a synthetic layered silicate (smectite clay) widely used as a rheology modifier, thickener, stabilizer, suspension agent, and gelling agent. It is applied in cosmetics, personal care formulations, coatings, paints, inks, adhesives, pharmaceuticals, and advanced material research. It provides excellent viscosity control, suspension stability, and film-forming properties.
