Where are pearlescent pigments used?

Pearlescent pigments are widely used in cosmetic containers, all kinds of packaging, toys, decorative materials, various films and other plastic products.

Pearlescent pigments are composed of several metal oxides coated with a thin layer of mica. Changing the thin layer of metal oxide can produce different pearlescent effects.

The excellent chemical, thermal and mechanical properties of pearlescent pigments provide the possibility of a wide range of applications in paints, inks, plastics and a variety of fields. They provide a completely new color quality to these products. Pearlescent pigments are non-toxic and harmless to the human body.

Therefore, it can be used in food packaging and children's toys. Dilute acids and alkalis cannot attack pearlescent pigments. Pearlescent pigments are harmless to the environment because they are actually insoluble in water and do not contain any heavy metals, which is a grade that is harmless to water quality.

Pearlescent pigments do not burn, do not spontaneously combust, do not conduct electricity, and can withstand high temperatures of 800. Pearlescent pigments can also be used in reactive coatings in radiation-curing systems (electron beam curing, light-curing). The chemical structure of pearlescent pigments makes it have excellent dispersion properties and can be applied to water-based coatings.

Pearlescent pigments can be used in transparent and translucent plastic resins, and the use of pearlescent pigments can bring a fascinating visual effect of color. In general, the more transparent the resin, the better the luster and color effect of pearlescent pigments. For less transparent resins (PC, PVC, etc.), the processing characteristics of these resins also allow the pearlescent luster and hue to be fully revealed.

Pearlescent materials were first used in cosmetic packaging. Later extended to toys, car interiors. 3C trim. Refrigerator car handles. Mainly some decorative products.

The excellent chemical resistance and high temperature resistance of pearlescent pigments provide the possibility of a wide range of applications in coatings, inks, plastics and a variety of fields, and they provide a new color system and color quality for these products. Pearlescent pigments are low in heavy metals and meet the relevant safety standards, so they can be used in food packaging and children's toys. Acids and alkalis cannot attack pearlescent pigments at room temperature.

Pearlescent pigments cannot be burned, do not spontaneously combust, do not conduct electricity, and can withstand high temperatures of 600 800. Pearlescent pigments can also be used in reactive coatings in radiation-solid sailing systems (electron beam curing, light curing). The special surface chemical structure of pearlescent pigment makes it have excellent hydrophilicity, so it can be applied to water-based coatings, but the lipophilicity is poor, so when used in organic systems, there will be poor dispersion problems, and the pearlescent pigments need to be treated on the surface so that they can also be well used in organic systems.

Pearlescent pigments are a class of pigments that can show far-reaching, crystalline, pearl-like colors under light, such as fish scale powder, bismuth oxychloride, alkali free lead carbonate, lead biarsenate, lead biphosphite and mica-type pearlescent pigments.

The light emitted by the metal is the whole metal surface, the refracted light and the reflected light should be different from the luster emitted by the pigment, the pigment is made by grinding the metal powder (such as silver arrow aluminum silver paste, silver arrow aluminum powder) aluminum sheets are measured in microns, and the gloss is definitely different from the former.

Pearlescent pigments are mainly divided into the following categories:

1.Pearlescent powder.

Pearlescent powder is divided into ordinary powdered pearlescent materials and pearlescent balls dispersed with soft resin, the colors are mainly silver, bright gold, metallic, rainbow interference color and chameleon series, among which pearlescent powder is distinguished by different particle sizes according to the direction of use and use effect, the smaller the particle size, the stronger the hiding power of pearlescent powder; The larger the particle size, the stronger the gloss of pearlescent powder; In the printing industry, there are strict requirements for particle size, small particle size can be used for offset printing, larger particle size can be used for flexo printing and gravure printing, and have better results.

2.Pearlescent pulp.

Pearlescent paste is a high viscosity pearlescent material, which is more suitable for mixing with offset printing ink, with excellent hiding power and good gloss, and is suitable for offset printing.

Fluorescent pigments are pigments based on thermosetting resins, with high tinting strength, strong fading resistance, ultra-fine particle size, and strong solvent resistance.

When irradiated, it can absorb a certain form of energy, and instead of converting it into heat energy, it excites photons to low visible light.

The energy absorbed by the form is released, resulting in the phenomenon of fluorescence in different hues. So in the daytime, it looks much brighter than other kinds of pigments.

But fluorescence is not noctilucent, noctilucent pink.

It is to absorb the light (sunlight or light) and release it in a dark place. Fluorescent pigments do not emit light in dark places. Of course, there are also customers who mix the two, so that they are bright during the day and wake up at night, and the effect is very good.
