|High retention of pigment is a substance that causes an object to take on color.high retention of pigments are soluble and insoluble, and there are differences between inorganic and organic.Inorganic pigments are generally mineral substances, and humans have long known the use of inorganic pigments, using colored earth and minerals, to paint and paint the body on the rock walls.Organic pigments are usually taken from plants and Marine animals, such as anise, gamboge and purple, which was extracted from shellfish in ancient Rome.|
A powdery substance used for coloring.Insoluble in water, grease, resin, organic solvent and other media, but can evenly disperse in these media and can make the medium coloring, and has a certain covering force.The basic requirements of the pigment used in art are that the finer the particles are the better, the brighter the color is, and the more durable and non-discoloration is the better (with better stability).Watercolors Watercolors are almost all transparent except for white.Only in this way can we meet the needs of watercolor dyeing.
Gouache was originally invented by adding white powder to watercolors to make them opaque.Because watercolor pigments are transparent, it is difficult to correct once a painting is wrong.Gouache, on the other hand, can be easily modified because of its opacity.Later, raw materials such as gum Arabic were added to gouache to further improve its performance.Arabic gum can give gouache a sheen after it dries, but in special situations where a flat coating is required (such as drawing renderings and coloring for animations), the gum can form irregular spots on the color surface or make the color uneven, so there are special deguming pigments.
Oil paints are paints diluted with oil.
Chinese high retention of pigment are very rich in various types, from mineral powder to plant extraction to animal extraction, the types are complex.
Theoretically speaking, as long as there are three primary colors of red, blue and yellow, all other colors can be mixed, but the color purity is always not high enough. Therefore, modern art pigment manufacturers produce high-purity pigments for various colors of hue and lightness to meet all kinds of needs.From the most basic 12 colors to the usual 24 and even 48 to more than 60 colors.And that doesn't include special metallic colors.Polymer Chemical Additive suppliers
