Functional Contributions of Sericite in Coating Systems
UV Shielding Function: Enhances the weather resistance of paint films and delays chalking and discoloration.
Two-Dimensional Flaky Structure with Layer-by-Layer Stacking: Improves water resistance, corrosion resistance, and impermeability of paint films; simultaneously enhances mechanical properties, crack resistance, acid resistance, alkali resistance, salt spray resistance, high-temperature resistance, and electrical insulation, thereby boosting the corrosion stability and electrical insulation of coatings.
Clay Mineral Characteristics: Exhibits excellent suspendability in water and organic solvents, improving the storage stability of coatings.
Functional Contributions of Mica Powder in Rubber
Two-Dimensional Flaky Structure with High Aspect Ratio: Improves the air tightness of tires.
Two-Dimensional Reinforcing Structure (Function): Replaces part of carbon black to reduce production costs.
Natural High-Wear-Resistant Material: Extends the service life of tires.
Smooth Mineral Properties: Delivers excellent demolding effect.
Performance Contributions of Mica in Modified Plastics
Improves Dimensional Stability of Thermoplastic Resins: Reduces shrinkage rate, inhibits warpage, increases heat distortion temperature, and enhances flexural modulus.
High Aspect Ratio Flaky Structure: Biaxial reinforcement ensures resin isotropy.
Insulating Material: Low magnetic content and high insulation performance meet the technical requirements of intelligent and electronic assembly applications.
One of Lightweight Modification Materials: Bulk density of mineral powder < 0.18 g/cm³.
