Pigments are one of the components of paints and enamels. Depend on the type of pigment color paint, its coverage, as well as resistance to weathering, chemicals and high temperatures. Pigments have a certain color, because they are able to selectively reflect the rays of daylight. When the pigment of the incident light beam, part of the radiant energy is absorbed, reflected and the other, staining pigment in the color of the reflected rays. The figure below shows the progress of the light rays incident on the surface, colored with paint, consisting of a binder and a mixture of various pigments. Part of the rays of daylight falling on the surface dye passes through the transparent binder for them, not coloring the film.
Another part of the rays reflected from the paint, and that creates a mirror effect, shiny surface (glare). Absorb some of the rays fully pigmented, and this point appears dark. Rays are absorbed selectively, one of the beams that make up the spectrum of natural light is absorbed, and dNaprimer when the pigment absorbs violet, blue, green, yellow rays, and reflects red and cursing reflected from the surface of the pigment and painted. then the surface is perceived as a dyed red. Pigment, which reflects nearly all light falling on it, it seems white, and pigment, which absorbs the incident on his light rays - black. The main colors should be considered as three - red, blue and yellow. Mixing them together, you get purple, orange, green.
In this way masking technique applying paint to the paint is the name of 'glazing'. It should be borne in mind that by mixing pigments together, we obtain uniform coloring paint, only when the density of this pigment are similar. Color Paint - Chromatic, a combination of black and white - achromatic colors. The chemical composition of the pigment causes its main properties: heat resistance, corrosion and chemical resistance, color.
