Yortay pearl pigments
Since ancient times human beings regard the pearl as one of the symbolic of beauty, because its unique and beautiful color luster bring people enjoy
the elegant color pleasantly. Yortay pearl powder are up to Taizhu pearl and Merck pearl powder, they can be very good equivalents to Taizhu pigments and Merck
pearlescent pigments.
From seventeenth Century onwards, the Europeans began to manufacture pearlescent pigment by using fish scale extract, mainly to satisfy the
need of the cosmetics industry. Nowadays, there are some expensive pearlescent luster pigments are still produced in this way, the main disadvantages are too high cost
and poor stability. Later on, imitations include bismuth oxychloride crystal and lead carbonate crystal, but the optical stability of the former is
poor, can not be durable; the latter is deadly poisonous.
During the years 1950 ~ 1960, the real practical and significant pearl pigment was developed. They are metal oxide or mica
pigments. Although we used to calling it pearl powder, but they are not purely is the pearl luster color in the range of the optical effect. Their performance
expand to a much wider range in the optical effects
Yortay mica powder can replace Taizhu pigments, Merck pearl powder. Yortay pigments, as special effect pigments,
is getting more and more applications in many industrial fields due to its unique and elegant luster, wide range of colors and particle size, the soft and
the sparkling pearl effect.
The cross-sectional of the pearlescent pigment is similar to the Pearl in the physical structure. The kernel is mica with low optical refractive
index, which are wrapped by the metal oxide, such as titanium oxide or iron oxide etc. The metal oxide are in high optical refractive index.
In the application of an ideal situation, pearlescent pigment uniformly disperse in the coating, parallellize to the material surface and form a
multilayer distribution, just as with the pearl. Therefore, the incident light will go through multiple reflection and nterference then the pearlescent
effect is performed. Yortay performance materials can be very good replacement to Taizhu effect pigments and Merck pearl powder.
Compared wth the traditional optical absorption type of organic and inorganic pigments, and optical reflection type of metallic pigments, the quality
principle of pearlescent pigments is totally different, so the pearl effect is unique. Pearlescent pigment is the main representative of
the three optical interference pigments. Yortay pearl powder are good Iriodin equivalents.
Pearlescent pigment with different particle sizes, can show different luster in paint, coaitng, plastic, ink, printing, wallpaper and other application. In
general, the larger particle size, the higher gloss, but the hiding power is weaker to the background color; and the smaller the particle, the
stronger hiding power to the background color and less glossiness.
Changing the thickness of the coated metal oxides on the kernel mica , the color wil vary accordingly. Warm metal color luster come up when mica was coated
by the iron oxide. There are different granular products available. Generally speaking, In addition, The advantages of pearlescent pigment lie in
its good physical and chemical properties, which is decided by its material composition:
- inorganic:
Stability, good resistance to temperature, light, acid and alkali.
- non metallic:
No heavy metals, chemical inertness, no harm to the environment and human body.
Judging from the above, pearlescent pigment is a kind of pigment with special good quality, providing a broad application of
color space, and the possibility of innovation for our life,. Yortay pearl powder are good coountertypes to Taizhu mica pigments and Merck,
Iriodin pearl powder.
As special effect pigments,its unique and elegant luster, and different colors and size caused gentle or shiny appearance, it
is getting more and more applications in many industrial fields. Due to the rapid growth of market demand,supply market of the pearlescent pigment changes very
rapidly. This kind of change in the near future, will not stop, but will aggravate. For the users of mca powder, they need to have a timely and
comprehensive understanding of the market supply situation, and accurately grasp the future change trend. So that they can make correct guidance to the
current purchase situation of pearlescent pigments, also they need to make the forecast for the future development of the pearl powder.
