Tintium High Performance Organic Pigments
Tintium Pigments made Harsha Chemicals are soft textured,
producing bright and clean shades with high tinting strength
and outstanding single pass dispensability in printing inks,
Paints, Plastics and other similar media.
Most of the yellow and Orange pigments used all over the
world are of Benzedrine (deceptively called diarylide) type
or of dangerous metals such as lead, chromium or cadmium. In
the case of benzidine (diarylide) Pigments, the azo compound
cleaves with biological fluids and the Carcinogen benzidine
is released.
TINTIUM series of specialty colorants are available
presently in two colours- reddish yellow XT 700 & XT 900 (
PY 139) and greenish yellow XT 500 (PY 185)
Tintium pigments are more easily dispersible than any other
comparable product.
Tintium is truly the future of the plastics Industry. It
serves in economical and environmental considerations as
well as weather fast properties
Tintum Pigments are among the best in the world for plastics
industry for spun fibers, films etc. Master batch
manufactures specially prefer TINTIUM products for their
excellent dispersibility and bright, clean colour. Due to
their high tinctorial strength TINTIUM saves money for the
users not insignificant.
TINTIUM pigments are migration resistant. Presently TINTIUM
XT 700 is used for up to 250 c and XT 500 for up to 240c.
For gravure inks which require more flow TINTIUM XT500
series may be advantageously used. Due to high tinctorial
value, smaller dosages may be used. There is no tendency to
crystallise in solvent medium. Though easy flowing, the ink
after application on the paper assumes thixotropy and hence
sharp images were the result. In metal decorating inks
Tintium withstands the temperatures involved with ease.
In flexo and screen inks due to the inherent stability to
solvents. Tintium are the pigments of choice.
In plastisol inks Tintium yellows reign supreme.
Tintium XT900 is a very soft opaque pigment (PY139) Which
gives opacity matching inorganic Pigments, but maintaining
the beauty of organic pigments XT900 is used in powder
coating, Out door finishes
Tintium for Plastics and polymers
Tintium XT700 series of pigment yellow 139 is best suited
for plastics. Its brilliant reddish and excellent
dispensability makes it highly attractive to plastics
Masterbatch Manufacturers. It is strongly recommended for
synthetic and natural rubber coloration also. No migration
takes place in plastcizers making it a product of choice fo
PVC / Plastisol manufacturers.
Tintium XT500 series is the greenish Yellow (PY 185) loved
by Plastics manufactures. Its attractive full tone and tint
tone shades are very clean.
Both the products are specially designed to resist change of
shade during processing.
Tintium series pigments are for use in everyday plastics and
injection moulding, Tintium pigments are dispersed easily
into the plastic by extrusion and using and adhension
promoter, (i.e) surface active agent or paraffin oil.
Tintium pigments are best suited for polymer coloration
because they are insoluble in the polymers under this
process conditions also. Blooming and bleeding which occur
due to migration are avoided by using Tintium. These
pigments also do not recrastallize causing structural
weakness or loss of hiding power.
Tintium pigments when used in packaging films are extraction
proof and physiologically safe. If transparent films aer
needed must be used.
The forte of Tintum pigments is the highly dispersibility
which gives value for money, besides the aesthetic look. The
polymers are glossier when Tintium is used.
Tintium pigments do not cause shrinkage when used in large
parts or products such as road dividers and milk crates. The
high light fatness of Tintium is a major advantage to
plastics exposed to bright sunlight like tarpaulins,
awnings, etc.
PVC and Tintium are made for each other. IN PVC wire
coating, Tintium is used to pass all standard tests for
dielectric strength and other electric properties .
Dispersion and suspension grade PVC can be colored with
Tintium and pigments dispersion is achieved by calendaring.
PVC cables colored with Tintium can with stand high voltage
(1100 Volts), and pass tests such as IS-694-1964 and
IS-5831-1970.
Polymer fibres such as polyolefin, polyester or Nylonfibres
can be colored in the melt with Tintium pigments. The fibre
strength remains unaffected. The fibers attain very good
gloss.
Extensive tests are being conducted by us with tintium in
various polymers for dispersibility, temperature stability,
particle size analysis ect. |
