Nano‑Modified Kaolin Clay is produced from selected high‑purity kaolin ore via ultrafine grinding and specialized nano‑scale surface modification treatment. Developed as a direct replacement for ASP 802, this mineral filler features narrow particle‑size distribution, outstanding whiteness and excellent polymer wettability. It serves as reinforcing and extending filler for high‑gloss industrial coatings and multiple engineering plastics, balancing surface gloss, scratch resistance and dimensional
Product DetailsThis nano‑modified kaolin clay adopts advanced wet‑process ultrafine pulverization followed by controlled surface modification procedure on kaolin particle surfaces. The modification treatment reduces the hydrophilicity of raw kaolin, improves the interfacial affinity between kaolin particles and organic resin matrix, and effectively inhibits agglomeration during high‑speed mixing and extrusion processing.
The product maintains consistent narrow particle‑size distribution and stable high whiteness. Low heavy‑metal content satisfies requirements for industrial coating and engineering plastic production. It provides prominent reinforcing performance, raising tensile strength, flexural modulus and heat‑distortion resistance of engineering plastic compounds without causing obvious loss of surface gloss. In high‑gloss coating systems, this kaolin filler optimizes suspension stability of paint slurry, reduces pigment settling tendency, improves scratch hardness of cured coating film, and helps to cut total formulation cost as an effective extender pigment.
It is compatible with solvent‑based coatings, high‑gloss industrial topcoats, powder coatings, PA, PBT, PET and other engineering plastic grades. Typical application scenarios include automotive component plastics, household appliance plastic parts, industrial machinery coatings and general‑purpose high‑gloss protective finishes.
For handling, avoid direct inhalation of fine powder. Keep the material sealed inside original packaging during storage. Store in cool and dry indoor warehouse, isolate from moisture, rain and direct sunlight. Recommended packaging is 25‑kilogram moisture‑proof woven bags. Do not stack the pallets excessively high to prevent bag rupture and powder caking.
