Pigments constitute the major class of colorants, the other being dyes. There are important differences between the two. Dyes are soluble in the medium in which they are applied (water, alcohol, wax etc.); pigments are insoluble. Pigments are dispersed, they do not form a true solution. Pigments are the colorants found in paints. They also are widely used to color inks and plastics. Unlike dyes, pigments do not have any substantivity (chemical attraction) for the materials they are used to color. They work by being evenly dispersed in a product and are held in place by physical means. In the case of paints, pigments are applied as a thin film (coating) and are fixed to the surface by a resin. In simple terms, they are glued to the surface. Pigments are crystalline particles consisting of hundreds to thousands of molecules. Dyes, when dissolved completely in a solution, exist as single molecules. Dyes are transparent; pigments range from transparent to opaque. Pigments generally have better fastness properties that dyes. They have better fade resistance and stability to chemicals. Pigments are comprised of two major groups – organic and inorganic. Organic pigments contain carbon as an element in the molecule. They tend to be transparent and constitute the majority of bright hues. Inorganic pigments tend to be opaque. Oxide pigments and titanium dioxide (white) are the most important inorganic pigments. They are robust and relatively inexpensive. Oxides generally lack the brightness of organic pigments. We offer both organic and inorganic pigments in dry (powder) form as well as liquid dispersions and pastes.
