Miraval® 5450 Cosmic Bronze

Miraval® 5450 Cosmic Bronze by Merck KGaA, Darmstadt Germany is an industrial pigment which offers coppery-sparkle interference color. It consists of synthetic calcium aluminum borosilicate (48-70%) coated with titanium dioxide (23-33%), silicone dioxide (5-11%), ferric oxide (2-6%) and stannic oxide (<2%). It combines unique purity of colors with high transparency and intensive reflective power. It shows special glitter effects and significantly reduces the visibility of flowlines. It creates brilliant sparkle combined with soft rainbow effects. It develops extremely smooth and optically perfect surfaces for optimum reflection. With its radiant luster and unusually brilliant shimmer, Miraval® 5450 Cosmic Bronze provides a touch of extravagance and color intensity to plastics applications.
