No hierarchy of the various processing methods and effect pigments Application

Optical properties of only one homogeneous material lamellae; having a layered structure and represented by two or more optical properties of the layered material composition different lamellae (film - metal structure of the pigment or non-multi-layer substrate pigment). No pigment layer structure is known metal effect pigments, such as aluminum or copper, crystal - zinc lamellae. Also a transparent effect pigments, such as BiOCl scaly crystal and polycrystalline TiO2 pigment also belong to this category. These scales are generally very thin metallic which can produce some interference colors. Lamellae with a substrate scales, this kind of non-metallic flake mechanical stability is low. plastic processing aid
Only a few species known to be crystalline or thin scaly substance, and its size and thickness suitable for production of the effect pigment. This form can not be crystallized substances, only in the thin lamellae on the support after treatment in order to become effect pigments, such supporting substrate or template called lamellae, on which the desired substance can be deposited. One of the most well-known example is the pearlescent pigments, ie natural or synthetic mica on mica platelets coated with a thin layer of TiO2 and Fe2O3. Transparent substrates can be easily and pigments absorb light pigment or even thicker coating layer with metal effect pigments. The advantage of the metal effect pigments in the actual application system with a strong hiding power. Transparent pearlescent pigment and opacity of the mixture of metallic pigments used in automotive coatings. If used as outdoor use, such as exterior automotive coatings and architectural coatings, surface treatment agent may be added to improve the weathering resistance of many effect pigments. pigments
Metallic effect pigments of the most important effects of non-film structure is undoubtedly the metallic effect pigments pigments. This pigment is made of aluminum, copper, copper - zinc alloy, zinc or other metals constituting scales or flakes. This effect is a metal pigment particle surface is formed on the light reflection phenomenon. When the edges and corners particle light scattering part of the increase, the effect will be seen in reduced gloss. Larger particle reflecting layer is better to produce a higher brightness and luster.
