The mass color (MC) of a coating is defined in ASTM Terminology Relating to Paint, Varnish, Lacquer, and Related Products (D 16) as: the color, when viewed by diffuse reflected light, of a pigment-vehicle mixture of such thickness as to obscure completely the background. Sometim…
BROADLY SPEAKING, the colored inorganic pigments are either lead chromates, metal oxides, sulfides, or sulfoselenides with a few miscellaneous pigments such as cobalt blue, ultramarine blue, iron blue, and bismuth vanadate yellow. This section describes the chemistry, manufactur…
Before entering into any discussion relating to pigments, it is first necessary to clearly define what is meant by a pigment as opposed to a dyestuff. In many earlier texts on color, the terms pigment and dyestuff are used almost interchangeably.
MIXING A PIGMENT WITH LINSEED OIL and making a paste is a preliminary test applied to pigments that has been in use in a systematic manner for almost a century and perhaps even longer in a less defined manner. Results from the test are usually qualitative in character and give a…
ALMOST EVERYTHING MAN-MADE that is white or light in color contains white pigment in its surface: houses inside and outside, industrial articles, plastics, glazes, rubber, printed surfaces, many paper products, and even some foods. Only papers and textiles can be white without p…
METALLICS PIGMENTS, INCLUDING ALUMINUM, zinc, gold, bronze, nickel, and stainless steel, provide the paint and coatings industry with a variety of aesthetic and functional properties. These pigments, either in flake or powder form, contribute to the metallic effects associated w…
BLACK PIGMENTS FALL INTO three classes [1] (Table 1). The first two classes derive their color characteristics from the element carbon, the third class from ferrous oxide, Fe3O4. Class 1 blacks are carbon blacks, which are composed of 90% or more of elemental carbon. Class 2 bla…
