The Realization Of Aesthetic And Artistic Performance Of Pearlescent Pigments
Mar 09, 2018

Today we introduce the pearlescent pigments. It is understood that 1942 American Afwood to use MICA and TiO2 synthetic pearlescent pigments, the 20th century 50-60 years, the real practical significance of the pearlescent pigment was developed, this is "Metal oxide/mica" pigments.

Although used to be called "pearlescent pigments", but the scope of the optical effect of such products is expanding more and more, it is not pure pearl color, such as Merck production of S-Class and L-class pigments, the naked eye can clearly observe its display of flashing luster; and irodin/afflair/ 300 and 5,002 series of products, its color is significantly different from the light pearl color concept. So for "metal oxides/mica" a class of pigments, people gradually began to call it "special effects pigments." First, the classification of pearlescent pigments the main types of pearlescent pigments are: natural scale pearlescent pigments, bismuth oxychloride crystal pearlescent pigments, mica coated pearlescent pigments. Currently the world's largest production and application of the most widely used pearlescent pigments, is based on natural mica flakes as the core (mica size from 4μm to 120μm, thickness of about 0.5μm), through a special chemical process, on its surface coated with a layer or multi-layer titanium or other metal oxides. Metal oxide Coated Mica film is very smooth, and therefore has a good light reflection performance, and transparent, that is, only a part of the light is reflected, the transmission part of the light through the mica film to reach another layer, can continue to be shot, resulting in many layers of reflection.
