Red copper bronze pigments

The KT-AC220RX through KT-AC1500RX series covers seven red copper metallic grades from 220 to 1500 mesh, formulated for solvent-based and oil-based coating systems. When evaluating a red copper powder sample for a decorative coating application, this particle size range maps from coarse, high-texture metallic finishes down to smooth, high-gloss copper sheens — all sharing the same warm copper/bronze metallic tone. These grades are not compatible with water-based systems due to oxidation sensitivity of the metallic flake substrate.
