Complex Inorganic Pigments Production and Properties
Ferro complex inorganic pigments are produced by homogeneously calcining metal oxides at 800 and 1300°C. The resulting product is ground into a fine powder. Each product offers a unique chemical compound with its own crystal structure.
These pigments have excellent heat and weather resistance, light fastness and opacity, and are chemically inert. They do not bleed or shrink. The natural properties possessed by the pigments provide a very wide range of application areas.
Applications include high-quality industrial coatings, coil coating, powder coatings, high-heat-resistant paints, water-resistant exterior facade paints, silicate paints, plasters and a wide variety of polymer types.
Most rutile and spinel pigments can be used without any restriction in food-contact applications such as food containers, plastic plates and toys.
The general properties of all pigments are as follows:
Sieve residue (45 μm) < 0.1%,
Water-soluble substances < 0.3%,
Volatile substances < 0.5%,
Heat resistance > 500°C,
(260°C for Violet 28-5333 pigment),
Light fastness > 7 (Blue scale),
Weather resistance > 4 (Grey scale),
Migration stability = excellent.
Cool Pigments: How does IR reflection work?
The wavelength and percentage distribution of solar rays reaching the earth is as follows (Figure 1):
