metallic mica powder

KT-303 is a Royal Gold natural mica pearlescent pigment in the 10–60μm particle size range — a deeper, more saturated gold tone than the standard KT-300 Gold Pearl grade, achieved through a higher iron oxide (Fe₂O₃) loading on the TiO₂-coated mica platelet. The warm, orange-toned gold body color is visible on any substrate without requiring a dark base — a key practical advantage over interference-only gold grades. At 10–60μm, KT-303 covers cosmetics, nail lacquer, decorative coatings, soap, and epoxy resin applications from a single grade specification.

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.
