‌Key Features & Advantages‌

1. ‌Unmatched Surface Enhancement‌

   • ‌High Gloss & Brightness:‌ A refractive index of 1.64 combined with ultra-fine particles (D50: 0.7–1.2 μm) ensures exceptional light reflection, delivering mirror-like finishes in coatings and plastics.
   • ‌Low Surface Defects:‌ Narrow particle size distribution minimizes surface pinholes, orange peel, and uneven textures, critical for automotive and luxury product coatings.
   • ‌Superior Dispersion:‌ Advanced surface treatment (e.g., silane coupling agents) ensures homogeneous distribution in both polar and non-polar matrices, reducing milling time and energy consumption.

2. ‌Enhanced Mechanical & Functional Performance‌

   • ‌High Hardness & Abrasion Resistance:‌ Reinforces polymer matrices to withstand wear in flooring, automotive parts, and industrial rubber components.
   • ‌Thermal Stability (>1,600°C):‌ Maintains integrity in high-temperature processes like injection molding and powder coating curing.
   • ‌Chemical Inertness:‌ Resistant to acids, alkalis, solvents, and UV radiation, ensuring longevity in harsh environments.

3. ‌Cost Efficiency & Sustainability‌

   • ‌TiO₂ Replacement:‌ Reduces reliance on titanium dioxide by up to 30% in white coatings and masterbatches while maintaining opacity and brightness.
   • ‌Low Oil Absorption (12–16 g/100g):‌ Minimizes binder demand, lowering formulation costs without compromising viscosity or curing speed.
   • ‌Eco-Compliance:‌ Heavy metal-free, REACH and RoHS compliant, and compatible with VOC-free and water-based systems.

4. ‌Process Optimization‌

   • ‌Reduced Cycle Times:‌ Excellent flow properties enhance mold release and reduce cycle times in plastics and rubber processing.
   • ‌Broad Compatibility:‌ Works seamlessly with epoxy, polyurethane, acrylic, silicone, and thermoplastic resins.
