the principle of color pearlescent pigment
Cross section of pearlescent pigment is similar to that of the physical structure of the Pearl. The kernel is low optical refractive index of mica, wrapped in the outer layer is the metal oxides of high refractive index, such as titanium oxide or iron oxide.
Applied under the ideal condition, the pearlescent pigments are uniformly dispersed in the coating, and parallel to the material surface forming a multilayer distribution and presence of pearls in the same, the incident light will by multiple reflections, interference reflects the pearlescent effect.
Organic and inorganic pigment and an optical reflection type metal pigment and conventional optical absorption compared, the principle of the fineness of the pearlescent pigments are completely different, so the effect is unique. Pearlescent pigment is the main representative of three feet above the full optical interference pigments.
Pearlescent pigments with particles of different sizes, the effect is different in use. In general, the larger particles, scintillation effect stronger, and on the background of the hiding power is weak; on the contrary, the particles smaller, on the background of the hiding power is strong, gloss more gentle.
Change the thickness of the metal oxide, or the type of metal oxide, will bring color changes.
Please the buyer orders in detail before consulting service, such as intention, to the customer requirements 200-300 grams of sample trial version (limited to color masterbatch, freight to be buyers themselves). Debugging process such as non expected, please inform, Meidi technology consultant will sincerely help your products to achieve the best effect.
