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, only0.01-0.015μ M, compared with opaque one. The small size of nanometer crystals gives transparent iron oxide larger 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.
Product Characters:
1. Excellent UV-light absorbing capacity.
2. Light fastness, weather fastness.
3. Excellent transparency, non-toxic and no color migratory.
4. Colors: Red, yellow and brown; Can be used in combination with organic transparent pigment.
5. Thermal stability: 160° C for transparent yellow; 300° C for transparent red and brown.
Product Application:
Used with aluminum pigments and pearl powder in the oil-based and water-based systems to produce golden colors and used with organic transparent pigments to produce various transparent paints
Soft color, no fading, prevent ultraviolet radiation from damaging the wood.
Coats on metal surface to produce gold or copper color, widely applicable for inner and outer coating of cans.
Vivid transparent colors suitable for the printing of aluminum foils.
Color can be kept for long periods of time.
Used in PET or PP plastic to make drinking cans and drug bottles.
Widely applied in the cosmetics industry because it is non-toxic and has an excellent absorption capability to ultraviolet radiation.
For transparent iron oxide red and brown, no change in color when the temperature is under 300° C.
