Iriodin® is the classic effect pigment. The mica-based pearl luster pigments from Merck refine coatings for interior and exterior applications. In doing so, they create unique luster and color effects which otherwise only occur in nature – from silver-white, red and bronze-colored earth tones and interference to gold luster. The effect varies from silky smooth to glittery, depending on the particle size distribution. The interplay between transparency, refraction and multiple reflection determines the enormous variety of effects.
As shiny as pearl and mother-of-pearl
They certainly live up to their name: Iriodin® pearl luster pigments consist of thin platelets of the natural material mica, coated in a wafer-thin layer of metal oxide. This creates semi-transparent pigments which give a coating the soft, deep luster that is characteristic of pearls and mother-of-pearl.
With its outstanding visual and technical properties, Iriodin® is used in a wide range of coating applications, especially in the automotive sector, architecture and other industrial sectors. Iriodin® pigments are also offered with an additional coating layer especially for exterior applications. These weather-resistant pigments thus fulfil the highest requirements of reproducibility and lasting color consistency.
