Optical and technical properties of color pigments
Color pigments
Durable and vibrant colors cannot be taken for granted. Organic and inorganic pigments give paints and coatings their radiant colors and make objects look their best. Furthermore, high-quality pigments are able to protect items and help them withstand even the most demanding of conditions.
Whether it's printing inks or industrial paints - organic and inorganic color pigments are able to bring radiance and vibrancy to virtually any surface – be it plastics, textile or other kinds of materials.
As a leading supplier of specialty chemicals, TER Chemicals works with highly reliable manufacturers to deliver premium products for your needs.
Color pigments are divided into organic and inorganic categories. Inorganic color pigments are typically insoluble oxides or sulfides of transition metals. Most inorganic color pigments are synthetically produced, but there are also naturally occurring variations such as ochre, which can be used in various applications. Iron oxide pigments represent the most significant and widely used class of inorganic pigments. Compared to organic pigments, inorganic pigments generally offer better opacity, higher weather resistance, and temperature stability, but exhibit lower brilliance.
Organic pigments, which are typically more color-intensive and have a higher chroma compared to inorganic pigments, are classified based on their chemical structure. The most significant and commonly encountered category is azo pigments, with the remaining pigments grouped as polycyclic pigments. Organic pigments enable a wide range of brilliant color tones to be achieved. They are often post-treated to achieve specific application-related properties such as improved dispersibility or opacity.
Pigments are insoluble, color-producing substances that are typically finely ground and can be used in various applications. They absorb light of different wavelengths and reflect specific colors, which determines their appearance. Pigments can be organic or inorganic and often exhibit high color stability, making them suitable for various applications such as paints, inks, plastics, textiles, and cosmetics. The color properties of pigments are influenced by factors such as particle size, chemical composition, and surface treatment.
Industries
Color pigments are used in a wide range of applications, whenever a product's appearance needs to be adjusted. These include rubber, paints, printing inks, industrial paints, adhesives and sealants, construction chemicals and many more.
