1. Definition and Process
Ablative Kaolin 4000 mesh is an ultrafine powder (D50, about 3 microns or finer) produced using nanoscale or submicron process technology. Its manufacturing process combines precise sorting and surface treatment, making it a technology-intensive, high value-added product.
2. Core physical and chemical properties
-
Fineness: 4000 mesh (about 3.5 microns) or higher, reaching the sub-micron level.
-
White identity: extremely high, usually ≥ 95%, excellent gloss effect.
-
Oil absorption: Very low.
-
Performance characteristics: It is characterized by extremely high specific surface area, excellent transparency or concealment (depending on the application system), strong enhancement effects, and excellent rheological control.

3. Key performance benefits
-
Ultimate performance: Provides intensification without significantly affecting transparency in clear or high-gloss systems, or strong concealment in tinted systems.
-
Superior surface quality: Enables coatings or products to achieve a mirror-like shine and smoothness.
-
Efficient rheological modification: Effectively control the thixotropy and stability of the system.
-
High functional potential: It can be used as a functional carrier for special composite materials.
4. Main application areas
-
Top industrial coatings: high-end automotive topcoats, UV-curable coatings, etc.
-
High-end specialty plastics: optical grade plastic films, high-performance composite materials.
-
Appearance: foundation, sunscreen, etc., as texture modifiers and fillers.
-
Special ink: high-precision printing ink.
-
Electronic data: high-performance thermally conductive insulation composites, electronic packaging materials, etc.
5. Use Suggested
High Shear Dispersion Equipment (e.g., high-speed homogenizers, basket mills) combined with efficient dispersant packaging is essential to overcome nanoparticle aggregation and achieve perfect diffusion. Strict formulation compatibility testing is recommended.
