Holographic Pigments (also call Spetraflair Pigments)
Applications :
Decorative effects for coatings, plastics, textiles, and packaging
Custom applications for automotive and consumer products
Holographic pigments includes multilayer flakes that give paints, coatings, plastics, textiles, and packaging the ability to change color when viewed from different angles. It is suitable wherever color is valued as a differentiator. Each flake exhibits a variety of colors depending on the angle at which it is viewed and the angle of incident light. The pigment’s dramatic color effect is visible even when styled in a variety of light and dark colors. It is easily incorporated into paints and plastics used in automobiles, consumer electronics, sports equipment, apparel, and packaging for luxury goods.
Holographic Pigments is a multilayer pigment manufactured by the deposition of ultra-thin layers using physical vacuum deposition (PVD). Holographic pigments are opaque and highly specular (mirror-like) due to a center aluminum core layer. Changing the surface texture of the glass-like layer in the pigment’s flake structure produces different effects: from neutral silver to a multi-color rainbow. As a result, all two grades of holographic pigments are made from the same two ingredients, magnesium fluoride and aluminum. To maintain the tight color tolerance
required by the automotive industry, the layer thicknesses are controlled to within
a few atoms using a proprietary manufacturing process.
Holographic Pigment Grades
Silver DM635 and DM620 pigments create the appearance of a diffractive rainbow moving over a silvery metallic base. DM635 offers the most dramatic effect with an average particle size of 35 microns.
