Blue pigments. Glaze Masking – an artificial pigment having the form of a dark blue powder, it is resistant to weak acids, but not resistant to alkalis. Therefore, it is not used in the paint for application on plaster, paint and slightly alkaline (latex). It is a complex cyanide of iron and alkali metal. Cobalt Blue – contains salts of cobalt and aluminum, obtained by calcination at a temperature = 1350 degrees Celsius.

Svetostoek, resistant to the action of alkalis and acids. Accelerates the drying of oil paints. Able to withstand high temperatures and used for dyeing and hot surfaces. Ultramarine – a product of burning a mixture of kaolin + quartz + ash (from blue to pale azure tones). Prussian blue – bright blue pigment (iron salt ferrocyanide acid).

Green pigments. Chromium oxide – a pigment of dark-green color, insoluble in alkalis and acids. It is used for the preparation of chemically stable, heat-and weatherproof paints (eg primer VL-02). Its chemical composition – chromium oxide with small amounts of soluble salts. Density – 4.6 – 5.2 g / cc., Melting point – 19900 S. Learn more at this site: Amazon. Emerald Greens – Chromium hydroxide. Copperhead – basic acetate of copper salt. Its often used with white lead. Blackens from hydrogen sulfide. Under the action of light alters turquoise to bright green. In addition, the use emerald green, lead, pinkovuyu. Black pigments. Soot stove, oil, gas – a product of incomplete combustion of various carbonaceous materials, is almost pure carbon. It has high weathering and lightfastness. Burnt bone – contains in its composition 10% carbon. 84% calcium, 6% calcium carbonate. It turns out firing, no air, low-fat gruboizmelchennyh bones. Metallic pigments, or bronze. Powders are finely ground in special mills, copper, aluminum, alloys nickel and zinc (Melchior) and other non-ferrous metals. Unlike mineral pigments, bronze powders are characterized by metal plate form particles. Through this form, these particles form a coating scaly surface, well protected base material from corrosion. For the main shades of bronze and silver are divided into gold. Bronze shades are obtained by chemical treatment of alcohol solutions with aniline dyes. These may be obtained from various shades of bronze: blue, purple, magenta. In the golden bronze metal scales should be polished in rotating drums with by fatty polishing compounds. Bronzing steel structures: bridges, farms, reservoirs, sculptures, etc. good protection from harmful external influences. Silver pigment – aluminum powder. Represents an almost pure aluminum and contains 3-4% wax that protects it from oxidation and eliminating the danger of explosion and samovozgaraniya. Brands PAC-1, PAC-2 PAC-3, PAC-4. Coverage Rate – 10 g / sq.m. Besides applying paint using exfoliated vermiculite (gold and silver). Artificial organic pigments. Organic dyes are usually distinguished from inorganic greater dispersion, a higher intensity and bright colors. However, light, temperature and chemical resistance of them worse. The most widely used are organic black pigments: Nigrosine, indulin; blue pigments: ortolotsianovy blue monastral, indatren; red pigments: lithologic, Shirley, Hansa yellow – lemon yellow with a greenish tinge, pigment red, blue, green. They are also used farblaki – pigments, obtained by deposition of aniline dyes in a white base, such as chalk and white.
