INFORMATION OF PEARL PIGMENTS
Review - Pearl Pigments
Pearl Pigments are very fine particle pigments in metallic, interference, pearlescent, halo and hi-lite colors. It
can be added to any art medium or used dry and over glazed making them a very useful basic color range for
your tool kit. A single jar of gold pigment can be used with white glue, acrylic mediums and gels, fabric paints,
clear stamp ink, watercolor and plain acrylic paints and varnishes, even wax, enamel paints and nail varnish
or dusted on tacky hot melt glue to make all kinds of finishing materials for indoor and outdoor applications
on anything from plastic and metal to polymer clay or paper.
Pearl Pigments are very fine powdered mica pigments that are non-toxic, inert, and can be mixed into virtually
any viscous, transparent medium and applied to any surface, Since they are not metals, they will never rust
or tarnish. The variety of finishes Pearl can produce is nearly endlessfrom metallic sheens to pearlescent
shimmers to all manner of faux finishes.
Since Pearl effect pigments are semitransparent; the use of different colored primers makes it possible to
achieve individual colors. The appearance depends on the viewing angle, resulting in a continually changing
impression.

Applications
Very fine pigment can be applied in thin layers to create smooth metallic coatings on almost any surface. The
pigments can be mixed with colored paints to deepen or contrast the pigment color. Pigments can be used
for many types of applications allowing the matching of color in fabrics, miniature building surfaces, wood,
plastic or metal surfaces. The pigments are dry, so they last for years and only small amounts are needed for
most projects. These pigments allow you to combine a metallic sheen with almost any color of craft, acrylic
or watercolor paint
APPLICATION IN PAINTS
Pearl fine pigments possess physical stability and can be used in water-based, solvent- based paints and
powder coatings. Pearlescent paints can be prepared by incorporating the proportioned amount of pearl
pigments into a clear lacquer or clear powder coating, this is the same for an enamel. Pearl luster pigments
are supplied in various grades and each leads to a particular effect. A suitable grade should be selected
according to the application. Pearl luster pigments are suitable for electrostatic coating. In addition they have
good acid and alkali resistance. Normal Concentration
The normal concentration of Pearl Pigments for paints depends on the types and shapes to be painted and
the painting or coating process. The following are normal concentrations used in various paints:
Paints
Automobiles
Construction Materials
Powder Coatings
Plastics
Concentration (%)
5-10
5-10
2-7
5-10
Remarks : Pre-mixture of Pearl Luster Pigments with a small amount of binder of binder paint or wetting
agent leads to good dispersibility.

APPLICATION IN PRINTING INKS
Pearl pigments are available for printing inks as conventional pigments. There are various to choose from
according to particle size range and should be selected according to the individual printing process. Pearl
inks can be easily prepared, by the incorporation of pearl fine pigments into the ink medium. Normal
Concentration
The concentration of pearl pigments in the ink medium depends on the printing process and article to be
printed.

Application in paper
Pearl fine pigments are suitable to be used in many kind of coated and specialty paper, such as advertisementused paper, name card paper, calendar paper, wall paper, and many kind of pearl luster packing paper. Pearl
luster effects with colors of silver white, golden, lustre effects are available.
Application in leather
Pearl fine pigments applied to leathers and PU/PVC synthetic leathers can be directly blend into inks to
use for printing on surface, also it can be added directly to transparent plastic resins to use for rolling and
scraping production.

f
For the finishing of all types of printing products and plastics
In combination with printing inks and coatings
In preprints and proof runs
Very good properties for packaging printing as they do not singe or migrate
They contain only trace elements of heavy metals
They are environmentally friendly and thus pose no problem with regard to waste incineration.

PRODUCT DEVELOPMENT INFORMATION
They are neutral in behavior in landfills because mineral pigments are insoluble in water and in solvents,
and do not decompose
They are chemically neutral
They are odorless and tasteless
They are stable up to temperatures of 450C to 800C
They are physiologically harmless; since they do not trigger toxic reactions, they are completely safe for
use in food packaging
They meet European REACH Standard
They contain no metal: the metal oxide used to coat the substrate has already been oxidized so there is no
risk of a reaction with oxygen. The pigments are therefore eminently suitable in cases where. electrical
conductivity during use is not desirable or where metal may not be used for legislative reasons
