Backed by decades of mineral processing expertise, Hengyuan empowers industries to achieve superior product aesthetics, durability, and cost efficiency.
Key Features & Advantages
Ultra-Fine Particle Size & Uniformity
- 1250 Mesh (5–7 μm D50): Enhances coating opacity, ceramic sintered density, and surface smoothness.
- Narrow Particle Size Distribution: Minimizes sedimentation in paints and improves green strength in ceramic bodies.
- High Surface Area (18–22 m²/g): Optimizes pigment spacing and UV resistance in high-solid coatings.
Superior Optical & Mechanical Properties
- Brightness (≥90% ISO): Critical for high-end ceramics, premium paints, and paper coatings.
- Low Iron Oxide (Fe₂O₃ ≤0.3%): Prevents yellowing and ensures whiteness retention in fired ceramics.
- High Mohs Hardness (2.5–3.0): Balances abrasion resistance and processability in extruded ceramic parts.
Enhanced Process Stability
- Low Viscosity Build-Up: Reduces thickener demand in waterborne coatings by 15–20%.
- Excellent Thermal Stability (Up to 1,750°C): Ideal for high-temperature ceramic firing without cracking or warping.
- Rapid Slip Casting Performance: Shortens dewatering time in sanitaryware and tableware production.
Sustainability & Compliance
- Eco-Friendly Processing: Zero wastewater discharge and 98% resource recovery via closed-loop systems.
- REACH & RoHS Compliant: Safe for food-contact ceramics, toy coatings, and architectural applications.
- Reduced Carbon Footprint: Energy-efficient calcination and drying processes lower CO₂ emissions by 30%.
Applications
Hengyuan 1250 Mesh Kaolin is a versatile additive across industries:
1. Coatings & Paints
- Architectural Coatings: Improves scrub resistance, hiding power, and weatherability in interior/exterior emulsions.
- Industrial Coatings: Enhances corrosion protection and gloss retention in automotive primers, marine coatings, and powder coatings.
- Wood & Furniture Coatings: Delivers smooth finish and stain resistance in UV-curable varnishes.
2. Ceramics & Sanitaryware
- Porcelain Tiles: Boosts mechanical strength, thermal shock resistance, and polished surface quality.
- Sanitaryware (Sinks, Toilets): Optimizes slip casting rates and reduces firing defects like pinholes.
- Technical Ceramics: Serves as a cost-effective filler in electrical insulators, refractory bricks, and catalyst supports.
3. Specialty Applications
- Plastics & Rubber: Improves tensile strength and dimensional stability in PVC cables, EPDM seals, and thermoplastic composites.
- Cosmetics & Pharmaceuticals: Acts as a gentle absorbent in foundations, creams, and tablet coatings (meets USP/EP standards).
- Paper Coatings: Enhances printability and brightness in high-quality packaging and graphic papers.
