Blue is Synthetic Inorganic. It is a blue pigment of sodium aluminosilicate
containing sulphur. It is prepared by heating kaolin, sodium carbonate,
sulphur and other inexpensive ingredients together. It is heat and alkali
resistant. It is used for optical whiteness in plastics, rubber, inks,
paints, cosmetics, detergents, cement, textile and paper.
Being a consumer product, Ultramarine is used for brightening the white
cotton cloth after washing and to provide blue color and brightness to
plastics and rubber used in the industries. It acts as a brightening agent
in white washing and is the only ultramarine blue pigment that does not fade
under sunlight or heat
(UPTO 350 DEGREES). It also has various other usage.
- As blue colorant in master batches and plastic resins.
- As an optical whitener on fabric, paper, plastics, rubber and paints.
- As blue colorant in printing inks.
- Finer qualities are used in painting and engraving
- Ultramarine Blue is 50% used for laundry, 40% for the white washes on
exterior surface and 10% for the Industrial use.
non-shrinking, non-warping nature of ultramarine blue, along with its
exceptional heat and light stability has led to the development of a range
of high quality ultramarine blue pigments specifically for masterbatchs
applications. This pigment is widely used in applications that require
improved appearance as regards brightness, transparency, surface smoothness.
this color masterbatch also provides improved mechanical properties
preferred for manufacturing of thin films, pressure pipes, fibres, bottles,
Further, the leather industry uses sodium bisulfite to make finished
leather products more wearable, waterproof and longer lasting. In addition
to its use as a food preservative, the food industry also uses sodium
bisulfite as a bleaching agent. Additionally, metal workers use sodium
bisulfite to finish metals.
Blue are suitable for use in inks due to their inorganic pigment nature.
They show good wettability in water systems and good resistance to organic
solvents. Moreover, properties such as good light resistance and low oil
absorption allow Ultramarine Blue to be used in different types of inks e.g.
Blue is used in a variety of paints for Oil Paints, Water and Acrylic
Paints, water-based Emulsion Paints etc. It provides a bluish undertone,
while providing uniformity in the composition. Ultramarine Blue pigment it
displays high fastness to alkalis, air, light, water, detergents and organic
Ultramarine Blue occupies a unique position in the blue color space that
can not be achieved by any other pigment or blend of pigments. The reddish
undertone of Ultramarine Blue, highly appreciated both in mass tone and tint
applications in surface coating. This makes the pigment clearly
differentiated from any Blue Phthalocyanine and any Cobalt Blue, even if
they are in combination with organic violet pigments.
Plastic & Rubber
pigment is used to provide a reddish blue shade or to whiten polymers. It
also works to provide a blue undertone to grey and black plastic parts. They
are compatible and suitable for all kinds of polymers, from polyolefins to
engineering polymers, including rubber as well. The fine particles of the
Ultramarine blue maintains dimensional stability of polyolefins and other
polymers, so that warping and shrinking do not take place.
is used in paper industry for whitening of cellulose pulp and the coloration
of the outside coating on coloured and stucco papers. Some manufacturers
used a blend of Ultramarine Blue and a optical whitener to achieve affect
optical whitening especially under a light which is rich in ultraviolet
rays. Both products are very compatible and do not present any problem.
Toiletries & Cosmetics
Pigments is used in many types of Toiletries formulations e.g. shampoos,
soaps, gels.It is much valued in cosmetics for their brightness, their
non-irritability characteristic and the very low levels of any impurity.
Some examples of fields of application are eye shadows, face powders and
