Technical Information

　　Careful control of the preparation process for Genky Trans-oxide pigments results in the formation of pigments with very small primary particle sizes. The particles are acicular with needle lengths of up to 43nm and needle widths up to 9nm.Typical specific surface is 105-150m²/g.
　　 The Genky Trans-oxide pigment range exhibit high levels of transparency and color strength combined with excellent chemical stability, acid-resistance, and alkaline-resistance. Genky Trans-oxides are strong absorbers of ultraviolet radiation. As inorganic pigments, they are non-bleeding, non-migratory and are not soluble allowing good effects to be achieved in both water and solvent based systems. Genky Trans-oxide pigments have good stability to temperature. The red can suffer up to 300℃, and yellow, green, black and brown up to be 160℃.
　　 According to the analysis by authority agency, the heavy metal contents such as Pb, Sb, Cd are under 100ppm, which meet the EN71(1994) Part 3 specification and proves our products are high quality environmentally acceptable materials.
