Key Features & Advantages
Ultrafine Particle Size & Uniformity
- 4000 Mesh Fineness (D97 ≤5 µm): Enables seamless integration into coatings, reducing surface roughness and enhancing gloss.
- Narrow Particle Distribution: Minimizes agglomeration for improved dispersion and stability in high-PVC formulations.
- High Surface Area (18–22 m²/g): Optimizes pigment spacing and TiO₂ extension, reducing raw material costs without sacrificing coverage.
Exceptional Optical & Mechanical Properties
- High Brightness (GE Whiteness ≥90%): Delivers brilliant whiteness and opacity, ideal for premium interior/exterior paints.
- Low Abrasion (Mohs Hardness 2–2.5): Protects processing equipment and extends the lifespan of mixers, pumps, and spray systems.
- Enhanced Film Strength: Improves scrub resistance (ASTM D2486) and adhesion (ASTM D3359) in waterborne coatings.
Superior Rheological Control
- Controlled Viscosity: Thixotropic behavior ensures optimal flow and leveling, eliminating sagging in vertical applications.
- Low Oil Absorption (30–40 g/100g): Reduces binder demand, enabling higher filler loadings while maintaining film integrity.
- pH Stability (6.5–8.0): Compatible with a wide range of resins, including acrylics, epoxies, alkyds, and polyurethanes.
Sustainability & Compliance
- Eco-Friendly Composition: Free from heavy metals (REACH, RoHS compliant) and suitable for low-VOC, APEO-free formulations.
- Energy-Efficient Production: Zibo Hongfang’s green manufacturing process reduces carbon footprint by 25% vs. conventional methods.
Applications
HY-T-80 excels in diverse coating and industrial applications:
1. Architectural & Decorative Coatings
- Interior Paints: Enhances opacity and touch-up uniformity in matte, eggshell, and semi-gloss emulsions.
- Exterior Paints: Improves weatherability, UV resistance, and dirt pickup resistance (DPUR) in elastomeric coatings.
- Primers: Boosts adhesion and filling power for wood, metal, and drywall substrates.
2. Industrial & Protective Coatings
- Anti-Corrosive Coatings: Acts as a functional filler in epoxy and polyurethane systems for pipelines, marine, and chemical storage tanks.
- Powder Coatings: Enhances flow properties and electrostatic spray efficiency in appliance and automotive finishes.
- High-Temperature Coatings: Stable up to 1,200°C, suitable for exhaust systems and industrial furnace coatings.
3. Specialty Coatings
- Automotive OEM/Refinish: Delivers smooth surface texture and chip resistance in basecoats and clearcoats.
- Wood & Furniture Coatings: Improves sandability and stain resistance in UV-curable varnishes and lacquers.
- Printing Inks: Provides rheology control and print sharpness in gravure and flexographic inks.
4. Beyond Coatings
- Plastics & Rubber: Enhances tensile strength and dimensional stability in PVC cables, EVA foams, and thermoplastic composites.
- Adhesives & Sealants: Improves thixotropy and gap-filling properties in construction adhesives and silicone sealants.
- Ceramics & Refractories: Serves as a fluxing agent in high-purity ceramic glazes and insulating materials.

Why Choose HY-T-80 Kaolin?
Technical Excellence
- Proprietary micronization and surface activation technologies ensure ultrafine particles with minimal grit content.
- Dedicated R&D team for custom modifications (e.g., hydrophobic treatment, particle size tuning).
Global Certifications
- Compliant with REACH, RoHS, ISO 9001, ISO 14001, and FDA (food-contact applications upon request).
Cost-Effective Performance
- Reduces TiO₂ usage by up to 20% in high-PVC formulations while maintaining opacity and color strength.
- Extends shelf life of coatings by inhibiting pigment settling and phase separation.
Sustainable Solutions
- Recyclable packaging (25 kg multi-layer paper bags or 1-ton FIBCs) with moisture-proof liners.
- Closed-loop water recycling system in production minimizes environmental impact.
Processing Guidelines
- Dispersion: Pre-mix with liquid media using high-shear dispersers (1,500–2,500 rpm) for 15–20 minutes. For solvent-based systems, add dispersants (e.g., polyphosphates) at 0.2–0.5% of kaolin weight.
- Formulation Tips:
- Water-Based Paints: Optimize at 5–25% loading to balance cost, viscosity, and film properties.
- Solvent-Based Coatings: Use 3–15% loading with compatible wetting agents to prevent flocculation.
- Storage: Store in a cool, dry environment (<30°C, RH <60%). Avoid prolonged exposure to moisture.
