What are the physical properties of organic paints?

Feb 24, 2016

 Pigment which were made from colored organic compounds were called organic paints.

   Brief introduction of organic paints:organic paints are a class of pigments, which are made of organic compounds, which have the characteristics of color and other series of pigments.Pigment properties including fast, water leaching, acid and alkali resistance, organic solvent resistance, heat resistance, stable crystal type, dispersion and hiding power etc.. The difference between organic paints and a dye is that it has no affinity with the colored object, only the organic pigment is attached to the object surface by the adhesive or the film forming material, or the object is mixed in the interior of the object, and the object is colored.The production of intermediates, production equipment as well as the synthesis process are muchness with dye production. So the organic pigment production in dye industry.Compared with General inorganic paints, organic paints usually have a high tinting strength, particles easily grinding and dispersion is not easy to precipitate, their color is bright, but their fast, heat resistance, weather resistance is poor. organic paints are widely used in inks, coatings, rubber products, plastic products, stationery and building materials material coloring.

   What are the physical properties of organic paints?

   The color of organic paints is distinctive,tinting strength is strong; they have no toxicity, but some varieties of light resistance, heat resistance, solvent resistance and resistance to migration are often not as good as inorganic paints.Varieties of colors is endless variations and colorful, but between the variety of colors exist certain inner link, once upon a time the colors are available three parameters to be determined, namely the hue, lightness and saturation.

   The color tone is the characteristic that the color is different from each other. It is determined by the composition of the light source and the sensation of the wavelength emitted from the object surface. It can distinguish the characteristics of red, yellow, green, blue, purple and so on.Lightness, also known as the brightness, it is expressed as changes in surface brightness characteristic value; by comparing the brightness of various colors. The color is bright and dark.Saturation also known as color, it is the value that the characteristics of object surface color shades. It makes the color bright and the dark. Hue, lightness and saturation constitute a three-dimensional, with the three establishment scale, we can use numbers to measure color. The nature of the color of the myriads of changes, but the most basic is red, yellow and blue,which are called primary colours.
