TRAFe–Transparent Iron Oxide

Description

Although nanometer transparent iron oxide is a kind of inorganic pigments in view of its synthetic and performance characteristics, it also owns properties of organic pigments. And transparent iron oxide belongs to nanometer crystals, because its particle size is much smaller, only 0.01-0.015?m, compared with opaque one. The small size of nanometer crystals gives transparent iron oxide large specific surface area (about 128m2/g), which results in its high oil absorption, (up to 80-100), by comparison, phthalocyanine blue 56, phthalocyanine green 46, carbazole violet 84, opaque iron oxide 18. Since the particle diameter of transparent iron oxide is smaller than half light wavelength, it has transparent colors when scattered in the media and made into successive films. Moreover, due to its tiny particle diameter, nanometer transparent iron oxide is totally different from the opaque one in aspect of light absorption and scattering, thus it has vivid colors instead of dark colors performed by opaque iron oxide.

Characteristics

1. Excellent absorption capacity to ultraviolet radiation.
2. light fastness, weather fastness
3. High transparency, non-migratory
4. Color: red, yellow and brown; can be used in combination with organic transparent pigments
5. Thermal stability: 160? for transparent yellow, brown; 300? for transparent red

Applications

1. Coatings for autos: used with aluminum pigments and pearl powder in the oil and water based systems to produce golden colors and used with organic transparent pigments to produce various transparent paints.
2. Coatings for wood wares: soft color, no fading, prevent ultraviolet radiation from damaging the wood.
3. Industrial coatings: coats on metal surface to produce gold or copper color, widely applicable for inner and outer coating of cans.
4. Printing inks: vivid transparent colors suitable for the printing of aluminum foils.
5. Decorative coatings: color can be kept for long periods of time
6. Plastic packing: used in PET or PP plastic to make drinking cans and drug bottles.
7. Cosmetics: widely applied in the cosmetics industry because it is toxin-free and has an excellent absorption capability to ultraviolet radiation.
8. Powder coatings:for transparent iron oxide red, no change in color when the temperature is under 300?
