Description:
Pigment Red 208 is a red pigment that can be used in inks, paints and coatings. Pigments are typically finely ground solid particles of color suspended in water or oil. Pigments are composed of a large number of small molecules called monomers. The chromophore group (a group of atoms) is the part of the molecule responsible for its color. Pigments will absorb some wavelengths of light and reflect others, giving them an appearance depending on their color. Pigments are also classified by their size, which is measured by the mean particle size using gel permeation chromatography (GPC). Pigment Red 208 is a nanosized pigment with an intramolecular hydrogen bond. It has a hydroxyl group and an inorganic metal ion as functional groups. The thermal expansion coefficient (TEC) for this product is 0.038x10-6/K at 25°C, which is higher than those for most organic products (0.0025
