In Mirach’s coating system. The three types of pigments used in architectural coatings are:

• Organic organic, which is the use of petroleum-based (carbon) chemical organic pigments to achieve bright, bold colors, but its carbon-based chemical structure usually degrades faster than inorganic pigments.

These pigments are more susceptible to changes in sunlight, moisture and temperature (heat cycle).

• Inorganic pigments, usually ceramic or metal mixed pigment inorganic pigments, come from mined and refined minerals, such as red oxides, or minerals synthesized at high temperatures, similar to combustion ceramics. These pigments are given colors that tend to be gray, brown, and soft red and yellow in the earth tones. With a few exceptions, inorganic pigments remain in their colours for years or even decades. One exception may be titanium dioxide (TiO2), which is usually used in white.

When mixing with other pigments, TiO2 must be carefully considered to ensure the expected performance.

• Metallic Luminescence, a fine sheet of aluminum or pigment mica consisting of a tiny piece of metal made of aluminum, natural mica, or synthetic mica material. Due to the size and shape of the metal sheets, they can produce departure light and glittering coatings. Some coatings with metal pigments also change color depending on the angle of view and light conditions.
