COLOR PIGMENT FOR CONCRETE

As the quality and performance of industrial products continue to improve, so do the demands on their appearance and durability. Therefore, there is a steadily increasing requirement for more durable pigments to color products such as paints, plastics, building materials and ceramics. The complex inorganic color pigments are of increasing importance to formulators, they need to satisfy the highest demands for heat stability, weather resistance and light fastness, while taking account of the ecological aspects of the end products. Up to now, the complex inorganic color pigments are the most stable class of pigments developed by the color industry.

Daylight Group Color Pigments for Concrete

Compounds that add pigment to the mixture are becoming increasingly prevalent and popular, as they infuse the concrete with hues more stable than paint. Pigments are fine dry powder or slurry or aqueous suspension that added to the concrete ingredients to produce colors, other than the normal grey color. It is added during batching as a liquid or finely divided colored inert powder. Wetness and alkalinity of concrete can be aggressive environment to pigments. That is why it is very important to use pigments designed for use in concrete. Plasticizers may be introduced to concrete mixture in which pigments are used in order to reduce water demand and other constituents that reduce the occurrence of surface efflorescence and minimize color fade caused by UV light.
