1. Liangjiang brand- lithopone, we strictly control operating conditions in the process of
production to guarantee the product quality. Our lithopone, with
strong covering powders. During the white pigments, the covering
powders, a little,second only to titanium dioxide, higher than zinc
white,lead white and antimony white. low oil absorption, alkali resistance and good chemical stability,
stable for a variety of gas;White color, but cheaper, non-toxic,
Mouldproof and kill alga; Good heat resistance and wearability.
As a traditional white pigment, lithopone is second only to
titanium dioxide ,white color, stong covering powers, good
dispersibility, resistance to pulverization, adhesion and
mouldproof, etc. There is a history of 100 years for the
development of lithopone. At present, only China in the world are
still in the production of lithopone, so China also reflects the
global trends. Shanghai Liangjiang titanium white products co.,
LTD., the production of lithopone, annual output of 60000 tons, the
export ratio is 41%, mainly used in coatings, and plastic fields,
accounts for about 93% of total consumption of lithopone. The
coating area about 77%, the plastic area about 16%.
2. Liangjiang brand, lithopone B302, adops pure physical and
chemical processing method for process selection of barium
sulfate), a mixture of zinc sulfide and barium sulfate, so they are
also called Charlton white. The appearance is white powder,
non-toxic, low oil absorption, alkali resistance, good chemical
stability, heat resistance and the good abrasion resistance. During
the white pigments, the hiding power next to titanium dioxide, not
including other mechanical impurities. It is the most superior
product quality performance as the similar products at current. So
widely used in paints, coatings, inks, primers, decorative
coatings, coil coatings, general industrial coatings, plastics,
rubbers, enamels, glasses, papers, clothes, leathers, water colors,
also used in polyolefin, vinyl resin, ABS resin, polystyrene,
polycarbonate, nylon and formaldehyde, and other fields.
High purity, Good dispersion, high temperature resistance, good
abrasion resistance and high hiding power.
Small particle size, it can improve all kinds of mechanical
properties of the products.
Low oil absorption, the good fluidity.
High Whiteness, neutra colour, it can keep stability of the palette
for a long time,and reduce the dosage of pigments.
Less impurities, no harmful substances, it can guarantee the safety
of products and the surface clean.
1. Applications: Widely used in paints, coatings, inks, primers,
decorative coatings, coil coatings, general industrial coatings,
plastics, rubbers, enamels, glasses, papers, clothes, leathers,
water colors, also used in polyolefin, vinyl resin, ABS resin,
polystyrene, polycarbonate, nylon and formaldehyde, and other
2. Liangjiang brand- lithopone, also called Charlton white(ZnS.BaSo4),
a mixture of zinc sulfide and barium sulfate. Lithopone is a kind of neutral dyestuffs, share with high acid
value instead of zinc oxide, in case of saponification in the
coatings. Lithopone, white color, strong hiding power, good dyeing
force, alkali resistant, heat resistant, but decomposition with
acid, darkness in light, poor weatherability and easy
pulverization. Widely used in indoor coating; Due to the effect of
atmospheric instability, It’s not be workable for outdoor paints.
In the interior economy flat paints, lithopone is commonly used to
replace parts of titanium dioxide as pigments, to decrease the cost
3. Liangjiang brand- lithopone, there are six kinds of type No.
according to different of surface treatment and zinc sulfide
content, as B301,B302,B301,C201,C202 and C303.
Different No.,different applications. Also do as customer’s
1. The quality request for lithopone, using in the production of
masterbatch, plastic, transparent fillings:
Because of the excellent nature in covering powder and whitness,
lithopone is second only to titanium dioxide. But the price of
lithopone is more cheaper than titanium dioxide. So lithopone is
often used to substitute for titanium dioxide, mixed with titanium
dioxide, can obtain excellent hiding power, high whiteness and
shading effect, and reduce the production cost.
Adding lithopone into the plastics, with good heat resistance,
light fastness, dispersion, and good tinting strength. It can
improve the quality of plastic parts, help to shorten the cycle of
plastic injection molding, also can increase the crystallinity of
thermoplastic polymer. Due to the characteristics of plastic
product, its use model should be considered for other coatings,
printing ink, paint, etc. In accordance with the technical
requirements of plastic products, to select a specific type of
(1) Good chemical stability, Liangjiang brand- lithopone,with a strong solvent resistance, good
heat resistance and so on. Good chemical stability in low
temperature and high temperature environment. It will not happen
with any additives in the masterbatch system of chemistry.
(2) Good temperature resistance, Because of the masterbatch in the manufacturing process and plastic
molding process is under the environment of high temperature,
lithopone should not change color in high temperature . Liangjiang
brand- lithopone B301, C201, C202, C303 have coated on the original
process, greatly improves the heat resistance and light resistance.
(3) Small Mobility, Due to the temperature of the plastic forming process ,there is a
big change, room temperature (raw material), high temperature
(processing), room temperature (cooling). Liangjiang brand
lithopone in high temperature or low temperature can not migrate,
adding liangjiang brand lithopone into plastic products ,the
surface colour is well-distributed.
2. Characteristic requirements for lithopone in coatings and paints .
High whitness, easy to spread, strong hiding power,
good fluidity and longer storage capacity.
Good particle size distribution, good dispersibility,
alkali resistance, good stability.
Good chemical stability, good dispersion, low oil
absorption,reducing the amount of pigment.
Heat resistance, alkali resistance,
good liquidity and covering power.
Increasing covering force, increasing the film thickness, surface
Liangjiang brand- lithopone, widely used in coatings, plays a very
important role in improving the coating thickness, surface
smoothness, heat resistance, alkali resistance, good dispersion,
good chemical stability. Because of its low oil absorption, a high degree of filling makes
it a good smoothing agent, and strengthen the flow of flat, so make
the coating cost reduction, can be used in waterborne coatings,
primer and intermediate coating, oil paint, etc. Use it instead of
15% ~ 30% of titanium dioxide in water paint,as a result, the white
degree increase, covering power did not go down .
3. Liangjiang brand lithopone, using in other fields:
Finish paints: Liangjiang brand lithopone, better than the most other fillers,
especially using in the chemical resistance coatings. The inertia
,organic coated.,excellent gloss and fidelity of the particles can
protect the paints from the long-term exposure, also increase the
surface hardness and color stability.
Woods and paints: Liangjiang brand lithopone, with chemical resistance, weather
resistance, low coherence, optical characteristics of low
dispersion and fine particles, especially suitable for paint paint,
varnish, paint, etc.
Paints and high build coatings: Liangjiang brand lithopone,the high filling can be applied to all
painting series, for example, primer, high build coating and other
types, as its low specific surface area and the division of
particle size and easy mobility, lithopone in the machining process
has low wear resistance and heat resistance. We recommend Lithopone
used for automatical primer surface, also keep a good uniformity
and smoothness ,even the high fillings.
adhesion agent: Liangjiang brand lithopone, good rheological property, high
filling and chemical resistance, lithopone is suitable for
adhesive, unsaturated polyester and polyurethane system, etc.
Printing inks: Liangjiang brand lithopone, with low wear resistance, high gloss
and color stability, low coherence, combined with its easy
liquidity makes lithopone suitable for printing inks with high
