Hengrui Brand High Whiteness 6000 Mesh Kaolin Ultra Fine for Paints and Coatings
Product Overview
Hengrui Brand High Whiteness 6000 Mesh Kaolin represents the pinnacle of mineral engineering, delivering an ultra-fine, nano-scale kaolin powder optimized for high-performance coatings, paints, and specialty applications. With a median particle size (D50) of 2–3 microns and a brightness exceeding 95% ISO, this ultra-pure hydrous aluminum silicate clay is processed using advanced delamination, micronization, and surface modification technologies. Designed to replace costly TiO₂ pigments while enhancing durability and rheological control, Hengrui’s 6000 Mesh Kaolin ensures unmatched opacity, scratch resistance, and color retention in waterborne, solvent-based, and powder coatings.
Ideal for manufacturers prioritizing sustainability and performance, this kaolin grade features ultra-low impurities (Fe₂O₃ ≤0.1%), exceptional dispersion stability, and compatibility with organic binders and inorganic additives. Whether formulating high-gloss automotive finishes, antimicrobial architectural coatings, or UV-resistant marine paints, Hengrui 6000 Mesh Kaolin provides a sustainable, cost-efficient solution that meets stringent global standards. Backed by cutting-edge mineral beneficiation and ISO-certified quality systems, Hengrui empowers industries to achieve superior product aesthetics, functionality, and environmental compliance.
Key Features & Advantages
Nano-Scale Particle Size & Uniformity
- 6000 Mesh (2–3 μm D50): Maximizes opacity and TiO₂ substitution (up to 20%) in high-solid coatings.
- Narrow Particle Distribution (Span <1.0): Minimizes agglomeration and ensures smooth film formation.
- High Surface Area (25–30 m²/g): Enhects pigment spacing, UV resistance, and barrier properties.
Unrivaled Optical Performance
- Brightness ≥95% ISO: Ideal for premium white and pastel coatings requiring brilliant whiteness.
- Low Yellowness Index (YI <1.0): Maintains color fidelity in UV-exposed outdoor applications.
- Gloss Enhancement (20° Gloss ≥85 GU): Delivers mirror-like finishes in automotive topcoats.
Enhanced Coating Durability
- Scrub Resistance (ASTM D2486): Withstands over 10,000 cycles in interior wall paints.
- Chemical Resistance: Stable in pH 4–10 environments, suitable for industrial maintenance coatings.
- Anti-Settling Properties: Reduces sagging and sedimentation in high-viscosity formulations.
Sustainability & Compliance
- Eco-Friendly Production: Zero-waste processing with 99% water recycling and carbon-neutral drying.
- REACH & RoHS Compliant: Safe for toys, food packaging, and eco-label-certified paints (e.g., EU Ecolabel).
- Reduced Carbon Footprint: 40% lower CO₂ emissions vs. conventional kaolin processing methods.
Applications
Hengrui 6000 Mesh Kaolin is a transformative additive across industries:
1. Architectural & Decorative Coatings
- Interior Emulsions: Enhects hiding power, washability, and mold resistance in low-VOC paints.
- Exterior Finishes: Improves weatherability, dirt pickup resistance, and chalk resistance.
- Textured Coatings: Provides smooth flow and anti-cracking in Venetian plasters and stuccos.
2. Industrial & Automotive Coatings
- Automotive OEM/Refinish: Boosts metallic flake orientation and UV stability in clearcoats.
- Powder Coatings: Reduces curing temperatures and improves edge coverage in appliance finishes.
- Marine & Protective Coatings: Enhects anti-corrosive properties and salt spray resistance.
3. Specialty Formulations
- Printing Inks: Delivers sharp print definition and rub resistance in offset and flexographic inks.
- Cosmetics: Acts as a silky matting agent in foundations, sunscreens, and CC creams (meets USP/EP standards).
- Plastics & Rubber: Improves tensile strength and EMI shielding in PVC cables and EVA composites.
