Industrial pigments are dispersed in paints to provide characteristics such as color, hiding power, bulk, durability, and corrosion resistance. They are available in many forms and colorant types. Common colors for industrial pigments include black, blue, bronze, brown, copper, gray, green, orange, purple, red, silver, white, and yellow. Pearlescent and photoluminescent products are also available. Important specifications for industrial pigments include pH and oil absorption, the amount of oil required to make paint with a pigment. Typically, oil absorption depends upon the size of the pigment particle, the type of binder, and the pigment’s physical and chemical properties. Smaller pigment particles require greater amounts of binder in order to cover larger surface areas and wet each of pigment particle.
Industrial pigments are available in several forms. Examples include dry powders, granules, liquids, pastes, pellets, and chips. Dry powders and granules are traditional forms that are available in the widest variety of grades. Free-flowing pourable liquids and high-viscosity pastes are master batches or concentrated dispersions of organic or waterborne pigments that contain solvents or diluents. They may also contain resins, additives or surfactants. Pellets and chips do not contain solvents, but may contain additives or plasticizers. These solid industrial pigments are easy to handle and feature a high pigment-to-binder ratio. Depending on the pigment and resin type, pigment levels of between 50% and 75% are achievable.
