Merck introduces new effect pigments

Merck has introduced three new effect pigments based on synthetic borosilicate flakes with a particle size of 10-100 µm. These include Miraval® 5320 Scenic Gold, Miraval® 5321 Scenic Copper, and Miraval® 5325 Scenic Turquoise.

The company says thatMiraval Scenic Gold is designed to reflect a luxurious look, while Miraval Scenic Copper offers warm red tones. Miraval Scenic Turquoise is said to reflect the colours of water. Merck adds that the special characteristics of the three new effect pigments are the intensively-colourful glittering highlights which create a particular brilliance.

The sparkling lustre and the reflections of light created by the Miraval effect pigments are claimed to refine packaging, such as tubes, films or coextruded bottles. The glitter effects and brilliance are much more intensive compared to the Iriodin® interference pigments. Merck says that the small particle size of the Miraval Scenic pigments allows good processing in various plastics applications. The new pigments set themselves apart by their high transparency and very good mechanical stability. Another special feature is that Miraval interference colours can be mixed with one another without the pigments losing their individual colourfulness. Due to the brilliance of Miraval, even small concentrations suffice to create eye-catching effects ranging from a star-like sparkle to a metallic character.
