About Colorants, Pigments and Dyes
Colorants, pigments and dyes are dispersed in paints and caulks 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 colorants, pigments and dyes 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 colorants, pigments and dyes 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.
