Lihat Profil SellerPremium Hydrophobic, Ultra-Fine Ground CaCO₃ for Enhanced Dispersion & Performance in Paints, Plastics, and Rubber
DERICOAT is a premium, surface-coated fine-ground calcium carbonate powder derived from high-purity white limestone. Engineered through a dry treatment process, it features a hydrophobic and dis-agglomerated surface for superior dispersion in polymer and coating systems. With ≥98.5% CaCO₃ purity, ultra-fine particle size (D50 = 2.0 µm), and low impurities, DERICOAT enhances gloss, opacity, mechanical strength, and processing efficiency. It enables cost-effective formulation by partially replacing resins and pigments while maintaining or improving product quality across paints, plastics, rubber, and composites.
Specifications
- Calcium Carbonate (CaCO₃) Content: ≥98.50% (Titration / XRF)
- Magnesium Oxide (MgO): ≤0.50% (ICP-OES)
- Iron Oxide (Fe₂O₃): ≤0.03% (ICP-OES)
- Median Particle Size (D50): 2.0 µm (Laser Diffraction (Malvern Mastersizer 2000))

- Oil Absorption: 14.0 g/100g (ASTM D281)
- pH (10% slurry): 9.0 ± 0.3 (ISO 787-9)
Applications
- Solvent-based and anticorrosive paints for improved opacity and durability
- Polyolefin masterbatches and PVC compounds (cables, rigid sheets)
- FRP and thermoset composites
- Rubber reinforcement in industrial parts, footwear, and latex products
- Plastic films and injection-molded components requiring stiffness and surface finish
Advantages
- Superior dispersion due to hydrophobic, dis-agglomerated surface treatment
- High brightness (94.5%) and color consistency from ultra-low iron content
- Reduces formulation costs by replacing expensive resins and TiO₂
- Improves mechanical properties: stiffness, impact resistance, tear strength
- Enhances surface finish, gloss, and flow characteristics
- Low oil absorption enables higher loading without viscosity issues
Processing Conditions
- Can be incorporated via standard dry blending or compounding processes
- Compatible with twin-screw extruders for masterbatch production
