Pearlescent pigments have a long history and a wide range of uses, the traditional pearlescent pigments include natural pearlescent and synthetic lead and bismuth, which are toxic and have limited use. With the advancement of science and technology, the new pearlescent powder is based on mica, flake quartz, flake alumina or flake glass powder, and its surface is coated with a layer of high refractive index metal oxide.

Among the many color-changing pigments, pearlescent pigments have a super high appearance, it has pearlescent decorative pigments, which are used in transparent and semi-transparent plastic resins, and the use of pearlescent pigments will bring an attractive color visual effect, so it is widely used in cosmetics, plastic industry, ink and paper printing, screen printing, etc. Pearlescent pigments are used in the coating industry, and can occur the effects of bicolor and angular heterochromia that cannot be achieved by other general pigments. With regard to pearlescent pigments with a flaky structure, horizontal arrangement in the coating prevents cracking, blocking ultraviolet rays, preventing moisture from penetrating and affecting the mechanical strength of the coating.

Pearlescent powder is applicable in most coating systems, and the pearlescent coating can be obtained by pre-wetting the appropriate amount of pearlescent pigment and then mixing it in the medium bright substrate and stirring evenly. Including oil-based, water-based, powder, UV curing, etc., such as automobiles, motorcycles, trains, bicycles and other transportation coatings; interior and exterior decorative architectural coatings; mobile phones, household appliances, daily necessities, computers, packaging containers and other plastic substrate coatings; furniture, decorations and other wood substrate coatings; artificial leather, leather, textiles and other surface coatings; industrial decorative coatings for metal and non-metallic substrates; powder coatings for household appliances and machinery; Body painting, oil painting and other art paints.

The method of applying pearlescent pigments to the coating is also relatively simple, when mixing the ink, a thickener is added to hinder the sedimentation or pre-wetting the pigment, and then dispersed in the connection to prevent condensation or sedimentation. Because mica titanium pearlescent pigments have outstanding dispersion ability, they create excellent conditions for ink production. It should be noted that pearlescent products can be used in combination with transparent dyes or pigments to obtain the same beautiful color effect, but if they are used in combination with non-transparent pigments, it will reduce the pearl luster. In the low-viscosity ink medium, the use of low-speed stirring can obtain outstanding dispersion effect, together with the use of other inks in the use of three-roller machine, high-speed mixer or ball mill and other equipment, otherwise it will lead to mica titanium pearlescent pigment particles are broken and lose luster.
