Special effect pigments are gaining more and more attention from industries because they allow obtaining peculiar optical effects, which can be exploited in many applications, from plastics and car coatings to the cosmetic field. The use of natural inorganic pigments dates to prehistoric times when natural ochre, charcoal and clays were used as colouring materials in cave paintings. It is the degree of these characteristics along with the thickness of the coating that determine the color and appearance of the pigment. The effect of zirconium oxide and quartz pigments on the heat and corrosion resistance properties of the silicone based coatings. The thickness of silica flakes is in the order of 400 nm, comparable to that of mica particles, and it can be tailored be so narrow to become itself an optical layer. Figure 2 shows an SEM image of one of the pigments used in this study. The low light stability, the high density and the poor mechanical properties these pigments have, limit their use in high-performance fields[5]. Pearlescent pigments have at least three layers of materials with different refractive indexes. It is then interesting to study the behaviour of commercial powder coatings with the addition of innovative special effects pigments, assessing the coating main properties after accelerated ageing treatments, such as UV and salt spray exposure[18][19][20]. GSB AL 631 Standard, “International quality regulations for the coating of building components – Aluminium”, GSB International e.V. This pigment is very expensive but shows some interesting features, such as low brittleness, high and soft luster together with very low density[9]. Nature 2000, 404, 980-982. In Ullmann’s Encyclopedia of Industrial Chemistry, 6th ed. From that point onward new discoveries were made in this field, as the production of aluminium-based pearlescent pigments in the 1990s[9]. Their semi-transparent nature and specular reflection work together to produce mother-of-pearl effects and interesting color travel combinations. When a white light beam encounters a pigment particle it is split into two different beams of complementary colours, differentiated according to the pigment thickness, which are one reflected and the other transmitted. Potassium aluminium silicate-based pearlescent pigments coated with Iron oxide (Type II) Coat. They may also be known as Mica Powders. Pearlescent pigments are usually micas, synthetic or natural that have been coated with titanium dioxide, iron oxide or another metal oxide. Pigments based on glass substrates play a minor role in the market because they are very thick and show limited optical properties, apart from special applications. Alumina (Al2O3) based pigments represent another type of emerging pearlescent pigment[5]. Powdered Pigments by Jacquard is a versatile, non-toxic additive for creating beautiful colors within your epoxy resin projects. Alumina-based pigments show the well-known advantages of mica-based pigments together with the ease of incorporation in many different binders as well as peculiar optical effects. Reflection and refraction mechanisms occurring at each interface cause shifts in the light wave coming off from the pigment, thus leading to interference mechanisms[5]. Topuz, B.B. 15 Colors Pearlescent Natural Mica Mineral Powder Epoxy Resin Dye Pearl Pigment. The protective properties of the coatings were assessed exploiting tests in aggressive environments and evaluating the degree of coating degradation according to established standards[24][25][26]. bailey anderson Dec 28, 2020. Thus, the pearlescent effect is produced by the specular reflection of a light beam from the different interfaces present through the pigment thickness. Among the special effect pigments, it is possible to count metal effect pigments and pearlescent pigments. The most widely used pearl pigments consist of mica platelets coated with titanium dioxide or iron oxide that give white and colored effects. Figure 1 – Simplified diagram showing the optical behaviour of pearlescent pigments constituted by a substrate and a high refractive coating. Pigments are substances used to modify the colour of a material, which, unlike dyes, are insoluble both in common solvents and binders. Org. refracted).
