- Brown Oxide exhibits a
richness of tone that is lacking in the blended
pigment and free from "streaking" which makes this product an excellent brown pigment.
- Brown Oxide contains magnetic y-iron oxide crystal form which
possesses improved stability over a blended form.
- Brown Oxide offers the
formulator a pigment providing the maximum in
most binder systems.
Use of Brown
Oxide
Paint Industries
- Brown Oxide pigment enjoys their widest use in coatings produced for
applications in marine environment. This
extensive use in marine coating is directly
related to excellent stability, chemical
resistance and low cost hiding power capability.
Corrosion and heat resistance makes the pigment
ideal for including in coating designed for use
on Steel and Iron Industries, boiler coatings,
automobiles and the likes etc.
- Brown Oxide pigment is
one of the few pigments which absorbs almost all
of the radiation in UV range and this absorption helps to prevent deterioration of the paint film.
Conversely it reflects a fair amount of IR light
which helps in Camouflage paints as it provides a reflectance similar to that given by trees, grass
and sand and thus prevents deterioration by aerial IR photography. Brown Oxide is an
excellent product for formulating compositions
that provide high IR reflectance and also for
designing camouflage colours.
Leather
Industries
Brown Oxide is an excellent pigment for Brown colour leathers as simulated leather because of trivalent chromium as one of its ingredient of composition . It keeps
the leather soft and supple and also used for
this purpose by Shoe Polish manufacturers.
Ceramic/Pottery
& Refractory Industries
Due to its special properties, Brown Oxide finds use in those
applications where a permanent inert pigment (of
relatively dull color) is called for. Hence, it is eminently suitable for coloring highly alkaline mixes used in ceramic, pottery and
refractory industries.
Wood, Plastics
& Handicrafts Industries
The rich Brown Oxide
colourants are ideal for contributing wood
graining effects to plastics or to printed panels
for building construction and cabinet work as
well as furniture stains and finishes.
Tiles, Flooring
& Cement Colors Industries
Since it contains Chromium , It is excellent for coloring highly
alkaline masonary mixes that must withstand
severe exterior exposures. It is used widely as a colourant in portland cement , in ceramic tiles,
concrete, lime proof and stucco paints and as a
pigment in roofing granules and flooring paint.
Rubber Industries
Brown Oxide is used in manufacture of Brown Rubber and Rubber
compositions because it can tolerate any type of
cure and has no tendency to degrade"(age)" the cured Rubber
compound.
Paper/Wall Paper
& Printing Inks
Brown Oxide pigment is
used in manufacture of paper, wall paper and
printing inks particularly for soap wrappers and
other similar applications.
Miscellaneous
Other Applications
Brown Oxide pigment
having excellent ferrite's properties makes the
product highly suitable for the manufacture of
magnetic and memory electronic devices. It is also used for foundry-core making. In polishing,
linoleum and asphalt etc.
