Paints, coatings, and inks all require pigments as key ingredients. In order to give the wet or dry film color, bulk, or other required physical and chemical properties, they are added to paint and coating formulas.
What Are Pigments?
When added to paint and coating compositions, pigments—finely ground, soluble natural or synthetic particles—add color. Additionally, they are employed to give the wet or dry film bulk or a particular physical or chemical characteristic. Organic, inorganic, functional, and special effect pigments are a few of the major classes of pigments.
Organic Pigments and Inorganic Pigments
Traditionally, organic pigments are transparent. Modern manufacturing methods can now add qualities that were previously only found in the chemical kind, such as the ability to create organic pigments with great opacity.
Inorganic pigments have been used since the earliest cave drawings, which date back 30,000 years. Despite the fact that they are naturally occurring, they typically need to be modified for the production of paint. There are many different colored pigments available, and all white pigments are inorganic.
Inorganic colors dissolve more readily in the resin than in biological pigments, which tend to clump together and create agglomerates. Special effect pigments produce visual effects like metallic, hammer finish, and different color perceptions depending on the angle, while functional fillers give the coating the desired quality like a corrosion inhibitor.
Difference between Dyes and Pigments
In the media in which they are spread, pigments—organic or inorganic, colored, white, or black materials—are essentially insoluble. Because they are different particles, the medium is colored and opaque.
Primary particles are the smallest units. The crystallinity of the pigment determines how these particles are shaped and structured. Primary particles frequently coalesce and produce agglomerates throughout the pigment manufacturing process. High shear is typically required to disperse the pigment into the polymer and break up these agglomerates. Therefore, pigments must be able to withstand solvents that they may come into touch with during application. Additionally, pigments must be resistant to light, weathering, heat, and chemicals like acids and alkalis depending on the requirements of the specific application.
Understanding the fact, the plastic pigment is up to three times brighter than non-fluorescent pigments, which make it a perfect choice in the plastic application where better clarity and brilliancy are needed.
