Top Grade Talc Powder for Paint and Coating Industries
Product Overview
Nanfeng Top Grade Talc Powder is a high-purity, micronized talc specifically engineered for the paint and coating industries. With a lamellar particle structure and 98% minimum purity, this product enhances coating performance by improving scratch resistance, sag control, and substrate adhesion while reducing formulation costs. Certified under ISO 3262, REACH, and TSCA standards, it is the ideal choice for water-based, solvent-borne, and powder coatings requiring precision flow properties and long-term durability.
Key advantages include:
- TiO₂ Replacement: Achieves 15–25% opacity enhancement with 10–20% loading.
- Halogen-Free Formula: Heavy metals (Pb/Cd/As) ≤5 ppm, asbestos-free (ISO 22262-1 verified).
- Thermal Stability: Withstands temperatures up to 900°C, suitable for high-bake systems.
- Sustainable Sourcing: Mined from ISO 14001-certified quarries with 80% renewable energy usage.
Key Features & Technical Benefits
1. Enhanced Coating Performance
- Sag Resistance: Enables wet film thickness up to 200 µm without sagging (ASTM D4400).
- Abrasion Resistance: 30% lower wear rate vs. calcium carbonate fillers (Taber abrasion, 1,000 cycles).
- Gloss Control: Adjustable 60° gloss from 5 GU (matte) to 85 GU (high-gloss) via particle size modulation.
2. Rheological Mastery
- Thixotropic Behavior: Reduces Stormer viscosity by 15–20 KU (ASTM D562) while maintaining anti-settling stability.
- Anti-Settling Efficiency: ≤0.3% sedimentation after 90 days (ISO 1524).
- Brush/Roll Resistance: Eliminates streaking in architectural paints (EN 13300 Class 1).
3. Environmental & Economic Efficiency
- VOC Reduction: Low oil absorption (18–22 g/100g) cuts resin demand by 12–18%.
- Recycled Content Compatibility: Stable performance in 30% post-consumer resin formulations.
- Carbon Footprint: 50% lower CO₂ emissions vs. synthetic fillers (ISO 14067 certified).
