Lithopone is a white pigment consisting of a mixture of barium
sulfate and zinc sulfide. It is used in interior paints and in some
enamels. It is widely used for white paint.
- It was
manufactured by Krebs Pigments and Chemical Company and other
companies.The material came in different "seals", which vary in
percent of zinc sulfide. Gold seal and Bronze seals contain 40-50%
zinc sulfide, offering more hiding power and strength.
- It is
produced by precipitation through filtering, heating and quenching
works. Lithopone has mostly been replaced by titanium dioxide which
is more durable, but it is much cheaper. It is used as a base for
lake pigment and used as a inert pigment for paint, ink and
cosmetics as well as in a large range of applications in plastic
industry. It is used as a filler in paper, leather, and linoleum.
- It is a
valuable pigment that is brilliant white with fine texture which is
advantageous vs white lead. It mixed well with oils such as linseed
oil or varnish, turns grey very fast in sunlight and white again in
the dark (due to actinium).
- The
brands of lithopone of the normal class, that of chemical
manufacture, are marketed under such names as Ponolith, Beckton
White, Jersey Lily White, Oleum White, Zinc Sulphide White, all of
these being of domestic manufacture, and their composition is of the
30 per cent. zinc sulphide type.
- The
lithopone preferred by the shade cloth trade would prove a failure
in the manufacture of oil paints and much more so, when used as a
pigment in the so-called enamel or varnish paints.
- Titanium
dioxide is one of the main raw material in the production of
emulsion paints. LITHOPONE can play a key role as an alternative,
with no loss of quality. Increasingly large quantities of LITHOPONE
are being incorporated into emulsion paints for this reason.
- An
emulsion paint modified using LITHOPONE as described above exhibits
equally good and in some cases actually better scattering power,
lightness, colour shade, viscosity, abrasion resistance and storage
stability than the original formulation.
-
LITHOPONE 30% L has a significantly lower specific surface area than
titanium dioxide and therefore requires less wetting agent to
achieve optimum wetting of its surface.
