Advantages of pearlescent pigments. [2][3] It is often caused by multiple reflections from two or more semi-transparent surfaces in which phase shift and interference of the reflections modulates the incidental light (by amplifying or attenuating some frequencies more than others). pearlescent paint. 2013. [5] A single iridescent species of gecko, Cnemaspis kolhapurensis, was identified in India in 2009. Original natural pearl essence is more expensive as compared to synthetic, mica-based effects.

Forward Pearlescent Pigment is a kind of flat powder. Our pearlescent pigment can either give off a soft shimmer or be sparkly and bright! FDA approved. pearlescent pigment 珠母涂料. Please help this article by looking for better, more reliable sources. They also have good chemical resistance. The production of pearlescent pigments is a very fine chemical processing process, and the quality requirements of the products far exceed the requirements for conventional inorganic materials and general fine chemical products. [7] In the case of diffraction, the entire rainbow of colours will typically be observed as the viewing angle changes. [13][14] It was later found that iridescence in the peacock is due to a complex photonic crystal. Their semi-transparent nature and specular reflection work together to produce mother-of-pearl effects and interesting color travel combinations. [16] Artificial pigments and paints showing an iridescent effect are often described as pearlescent, for example when used for car paints. Pearlescent Pigments.

Pearlescent pigments give off a sheen most reminiscent to natural pearls. A selection of pearlescent pigments with strong colour effect, a high degree of light fastness (non-fading) and excellent tolerance to a wide temperature and pH range. Pearlescent pigments are a versatile group of effect pigments that are widely used in many coatings applications. Pearlescent coatings or pigments possess optical effects that not only serve decorative purposes (such as cosmetics, printed products, industrial coatings, or automotive paints), but also provide important functional roles, such as security printing or optical filters. Iridescences based on multiple layers of cells are also found in the lycophyte Selaginella and several species of ferns. Pearl luster pigments Linguee. Pearlescent pigments, powders, dispersions and pastes from IFC Solutions are a new and creative type of food coloring used in a wide range of industries. Pearlescent Pigments offered by us are used for developing color through interference between light rays that reflects at specular angles from the top and bottom surfaces of the metal-oxide layer. Light refracts at different levels of the metals in the pigment. Addition usually begins with the harder-to-disperse organic pigments, followed by inorganic pigments, and lastly the pearlescents. They deliver superior whiteness, brilliance and coverage with extraordinary optical effects ranging from a fine-grained luster to a bold silvery white sparkle. The range of colours of natural iridescent objects can be narrow, for example shifting between two or three colours as the viewing angle changes,[5][6], Iridescence can also be created by diffraction. Examples of iridescence include soap bubbles, feathers, butterfly wings and seashell nacre, as well as certain minerals.It is often created by structural coloration (microstructures that interfere with light). Lustrous, iridescent, and angle-dependent optical effects are now commonplace and are to be found in many day to day products.These optical effects not only serve decorative purposes (such as cosmetics, printed products, industrial coatings, or car paints) but also provide important functional roles, such as security printing or optical filters. [22] Iridescence is known to be present among extinct lithornithids. Pearlescent pigments are composed of synthetic mica platelets or artificial glass substrates and consecutive semitransparent layers of metal oxides. Iridescence can for example be due to thin-film interference, the functional analogue of selective wavelength attenuation as seen with the Fabry–Pérot interferometer, and can be seen in oil films on water and soap bubbles. Translator. Pearlescent paints can be prepared by incorporating the proportioned amount of pearl pigments into a clear lacquer or clear powder coating, this is the same for an enamel. It is a partially transparent powder created from mineral mica and metal oxide. It is partially transparent powder created from combining layers of mineral mica with metal oxide.

Our products are featured with weather resistance, cosmetic and industrial non exterior grade of Pearlescent Pigments. The leaves of Southeast Asia's Begonia pavonina, or peacock begonia, appear iridescent azure to human observers due to each leaf's thinly layered photosynthetic structures called iridoplasts that absorb and bend light much like a film of oil over water.
