What is lithopone used for?

What is lithopone used for?

lithopone, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. Lithopone was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds.

How is lithopone manufactured?

Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide: BaS + ZnSO4→ ZnS · BaSO. This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4.

What is lithopone formula?

Lithopone | BaO5S2Zn2 – PubChem.

What is the use of paint?

It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor or synthetic. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid.

Is zinc a sulfide?

Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.

What are white pigments?

White pigments consist of natural or synthetic inorganic pigments. White pigments are used for white colors, tinting colors, and covering tones in paint. For opaque coverage, titanium dioxide is preferred because of its excellent hiding power.

What is the harmful effect of paint?

HARMFUL EFFECTS OF PAINT POLLUTION Prolonged or high exposure to paint and paint fumes can cause headaches, trigger allergies and asthmatic reactions, irritate skin, eyes and airways, and put increased stress on vital organs such as the heart.

Why is paint important?

Paint provides a protective coating that will preserve the interior or exterior surface. It enables such areas to withstand wear and tear while protecting walls from damaging effects of extreme weather conditions. Improving your home by applying paint will slow down the process of wear and tear.

Is zinc sulfide harmful?

Chronic: Zinc-containing fumes may cause metal fume fever. Sulfides may cause irritation to skin, Hydrogen sulfide, if generated, is toxic, a severe irritant and flammable. Effects include conjunctivitis, headache, nausea, dizziness, coughing, pulmonary edema and leading to death.

What can I do with zinc sulfide?

Zinc sulfide is also used as an infrared optical material, transmitting from visible wavelengths to just over 12 micrometers. It can be used planar as an optical window or shaped into a lens.

Is black a pigment?

Is black the absence of color? In science, black is the absence of light. And color is a phenomenon of light. But a black object or black images printed on white paper are made from pigment, not light.

What causes white pigments on skin?

Skin layers and melanin Vitiligo occurs when pigment-producing cells (melanocytes) die or stop producing melanin — the pigment that gives your skin, hair and eyes color. The involved patches of skin become lighter or white.

What is Lithopone 30% L?

This organically coated pigment is suitable for matt and semi-gloss coating systems and can be used as a masterbatch grade for synthetic polymers. We also produce Lithopone 30% L – which is suitable for natural elastomers, jointing and sealing compounds.

What is the use of Lithopone in coating?

Lithopone can also increase a coating’s lifetime by reducing in-film cracking and improving color retention. Our lithopone products include Lithopone 30% DS. This organically coated pigment is suitable for matt and semi-gloss coating systems and can be used as a masterbatch grade for synthetic polymers.

What are the benefits of Lithopone in plastics formulators?

Plastic formulators using lithopone can also expect an improvement in product quality. A combination of lithopone and TiO 2 can help reduce lacing and deliver an improvement in mechanical properties including higher ultimate elongation and impact strength.
