Metal Luster Series

Bulk bronze mica-based pigment delivers rich copper and earth-tone metallic finishes through iron oxide–coated natural mica. Our KT-500 Metal Luster Series spans three particle sizes—5–25 μm for smooth satin coverage, 10–60 μm for classic luster, and 10–100 μm for high-sparkle effects—all heat-stable to 800°C and fully TiO₂-free, making them suitable for coatings, automotive interiors, plastics, and cosmetic bronzers where you need consistent color at every viewing angle.

Bronze metallic mica powder delivers a warm, opaque earth-tone metallic finish through an iron oxide (Fe₂O₃) coating on natural muscovite mica — producing consistent color at every viewing angle, not just at specular reflection. Our KT-500 Metal Luster Series covers three particle size grades (5–25 μm through 10–100 μm) to match everything from fine satin coverage to high-sparkle flash effects. Heat stability to 800°C and a fully TiO₂-free composition make these grades relevant across coatings, plastics, inks, and cosmetics alike.

KT-532 is a natural mica-based flash red brown pigment coated with ferric oxide, delivering a warm, sparkling metallic luster with strong opacity — well suited for decorative coatings, epoxy floors, and cosmetic applications. Formulated as a cost-effective iriodin 532 alternative, it matches the same mica substrate, iron oxide chemistry, and particle size range as Merck's original, making it a straightforward drop-in for formulators already working with iriodin equivalents in their systems.

KT-510 is a natural mica-based iron oxide mica pigment delivering a rich coffee-brown metallic lustre with strong opacity — a direct functional equivalent to Merck pearlescent pigments in the Iriodin 510 series. Its warm, deep tone and consistent metallic finish make it a practical choice for decorative coatings, cosmetic formulations, and specialty printing applications.

KT-500 is a bronze mica pigment built on natural mica flakes coated with ferric oxide, delivering a warm, rich metallic luster with strong opacity — a direct functional match to the iriodin effect found in Merck's widely specified 500-series. Suited for decorative coatings, epoxy floors, and cosmetic formulations where consistent, high-coverage metallic bronze is required, KT-500 is a well-established iriodin 500 equivalent used by formulators across multiple industries.

KT-7573 is a coarse mica powder delivering a deep, warm wine red metallic effect built on a fluorphlogopite base — engineered for applications where coverage, sparkle, and color depth all matter. Compared to natural mica equivalents, it offers noticeably cleaner color, fewer surface defects, and stronger luster retention under demanding conditions. Widely used in epoxy floors, decorative coatings, and craft art where coarse particle brilliance is a design requirement.

KT-7511 is a bronze synthetic mica pigment built on a fluorphlogopite base coated with iron oxide, delivering a warm, rich metallic luster with strong coverage. Synthesized from high-purity fluorphlogopite, it outperforms natural mica in brightness, color consistency, and thermal stability. Well-suited for cosmetics, decorative coatings, and nail applications where clean metallic effects and reliable batch-to-batch performance matter.

KT-535 is a flash mauve pigment built on mica flakes coated with ferric oxide, delivering a warm, richly toned metallic shimmer with strong opacity. The iron oxide mica construction gives it reliable chemical and physical stability across demanding substrates. It performs consistently in automotive coatings, decorative paints, and cosmetic formulations where a deep mauve metallic effect is required.

KT-520 is a satin bronze pigment built on natural mica flakes uniformly coated with ferric oxide, delivering a warm, rich metallic luster with strong opacity — closer in character to a true metal finish than a conventional pearl. It performs across decorative coatings, cosmetic formulations, and nail applications where a controlled, non-glittery bronze tone is required. As a direct iron oxide mica solution in the fine 5–25μm range, it disperses cleanly into both solvent-borne and water-borne systems without surface treatment in most standard formulations.

KT-500 is a Bronze natural mica metallic pigment in the 10–60μm particle size range — a mica flake coated with iron oxide (Fe₂O₃) that produces a warm bronze metallic luster with strong opacifying/concealing properties and high chemical and physical stability. Unlike the KT-300 Gold Series which combines TiO₂ and iron oxide for a pearlescent gold effect, the KT-500 Metal Luster Series uses iron oxide alone on the mica substrate — producing a more opaque, warm metallic character with higher covering power and a distinctly different visual weight. At 10–60μm, KT-500 covers coatings, cosmetics, nail lacquer, soap, epoxy, and decorative craft applications from a single grade.

Kolortek's Metal Luster Pearlescent Pigments are iron oxide-coated mica flakes available in two substrate options: natural mica (KT-500 Series) and synthetic fluorphlogopite (KT-7500 Series). Both deliver warm metallic luster with strong opacity and reliable chemical stability. Color tone is controlled by varying the iron oxide coating thickness, producing a consistent range from gold to deep bronze across multiple particle size grades.
