Conclusion: Passed – Conforms to ZC-2023-MFB-002 standard.
Applications:
· Coatings & Paints – Coil coatings, high-temperature paints (barbecues, exhaust pipes), powder coatings, fluorocarbon paints, military camouflage coatings
· Plastics & Masterbatch – Engineering plastics, high-temperature plastics, food contact materials, agricultural films, outdoor plastic products
· Building Materials & Ceramics – Colored concrete, roof tiles, paving bricks, ceramic glazes, glass coloring
· Other Uses – High-temperature inks, solar collector coatings, cool roofing paints, foundry coatings
Process Advantages:
· Manufactured via high-temperature calcination (spinel synthesis process) ensuring uniform crystal structure
· Advanced milling and classification systems for consistent particle size distribution
· Free from heavy metals and toxic impurities, compliant with FDA, REACH, and RoHS standards
· Low oil absorption, reducing binder costs in coatings and plastics
· Excellent dispersion in both water-based and solvent-based systems
· Blue-phase black tone provides cleaner, deeper black than carbon black or iron oxide black
· Batch-to-batch color consistency with strict quality control
