Ferro pigments obtain their extraordinary properties through a combination of special manufacturing processes. These pigments are chemically inert and have excellent heat and weathering resistance, lightfastness and opacity. In most applications they are non-warping and non-bleeding. The inherent properties of the pigments allow for a wide range of end uses. Applications include many different kinds of polymers, high quality industrial coatings, coil coating, powder and high heat resistant coatings, weatherproof facade coatings, silicate coatings and stuccos. Due to the solid state reaction and, if necessary, a subsequent washing process, most pigments meet the high demands for heavy metal release. Therefore most of the rutile and spinel pigments may be used without restriction in direct food contact applications such as food containers, plastic dishes and toys.

The following data applies to all pigments mentioned in this chapter:
