White Washable 1250 Mesh Calcined Kaolin for Coating and Plastic - Superior Durability and Performance
Product Overview
Our White Washable 1250 Mesh Calcined Kaolin is a premium-grade mineral additive engineered to deliver exceptional performance in coatings, plastics, and various industrial applications. Through advanced calcination and micronization processes, we produce a high-purity, ultra-fine kaolin powder that offers superior whiteness, opacity, and mechanical reinforcement compared to conventional fillers.
This product is specifically designed to enhance product durability while serving as a cost-effective partial replacement for titanium dioxide (TiO₂). With its excellent dispersibility, suspension stability, and chemical inertness, it integrates seamlessly into water-based and solvent-based systems without compromising processing or final product quality.
Key Advantages & Product Features
1. Optimal Particle Distribution for Superior Performance
Uniform 1250 Mesh Fineness (D50 ≈ 10-12μm) – Ensures smooth texture and even dispersion.
High Whiteness (≥92% ISO Brightness) – Provides a clean, bright base for coatings and plastics.
Excellent Scattering Power & Opacity – Enhances hiding power in paints and films.
Strong Covering Ability – Reduces the need for excessive pigment loading.
2. Outstanding Dispersion & Processing Properties
Easy to Wet and Disperse – Minimizes agglomeration in waterborne & solvent-based systems.
Stable Suspension Performance – Prevents settling in liquid coatings and adhesives.
Improved Flowability – Enhances processing in plastics extrusion and injection molding.
3. Chemically Inert & Non-Reactive
No Chemical Reaction with resins, solvents, or additives.
pH-Neutral (6.5-7.5) – Compatible with most formulations without destabilization.
Excellent Acid/Alkali Resistance – Suitable for harsh industrial environments.
4. Enhanced Coating & Plastic Performance
Improves Scratch & Abrasion Resistance – Reinforces film hardness in coatings.
Boosts Weather Resistance – Reduces UV degradation in outdoor applications.
Increases Tensile Strength & Stiffness – Reinforces plastic and rubber composites.
5. Cost-Effective TiO₂ (Titanium Dioxide) Replacement
Partial Substitution (10-30%) of TiO₂ Possible – Lowers material costs without sacrificing opacity.
Maintains Color Vibrancy – Does not dull or yellow over time.
Sustainable & Eco-Friendly – Reduces reliance on high-carbon-footprint TiO₂ production.
