Lithopone B311

Liangjiang brand, lithopone B311, 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.

DESCRIPTION

1. 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 of coatings.

2. Liangjiang brand- lithopone, there are six kinds of type No. according to different of surface treatment and zinc sulfide content, as B301、B302、B311、C201、C202 and C303.

Different No.,different applications. Also do as customer’s request.

3. Liangjiang brand Lithopone- production progress：

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%.

MAIN FEATURES

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.

APPLICATIONS

1.Characteristic requirements for lithopone in coatings and paints

Applications	Characteristic requirements
water-based paint	High whitness, easy to spread, strong hiding power, good fluidity and longer storage capacity.
emulsion paint	Good particle size distribution, good dispersibility, alkali resistance, good stability.
