Product Name: Transparent Iron Oxide Pigment
Synonyms: Transparent Iron Oxide Yellow, Nano grade Transparent Iron Oxide Yellow, Transparent Iron Oxide Pigment, Trans Iron Oxide Yellow
Trans oxide yellow generates exceptional levels of transparency and durability, combined with excellent chemical stability and ultraviolet absorption properties. Coveted for their heavy-duty weather fastness, heat-resistance and strength in UV radiation absorption, trans oxide red represents an attractive product solution for a wide range of applications.
Being inorganic, non bleeding and non migratory, trans oxide yellow consistently yield superior results in both solvent and water borne systems. These essential properties make trans oxide yellow the perfect solution for most applications including wood finishes, artist colors, industrial coatings, plastics, cosmetics and automotive paints.

| Advantages︰ | 1. UV Absorptioin
Transparent iron oxide pigments are effective absorbers of ultraviolet radiation, providing essential protection to resins and many substrates. The inclusion of these pigments, even at low levels, ensures significant protection against degradation resulting from UV exposure.
2. Stability
Both acid and alkali resistant, transparent iron oxide pigments demonstrate outstanding weather fastness and gloss retention qualities. Yellow iron oxides exhibit thermal stability of approximately 160oC.Red grades, being a dehydrated form of yellow iron oxides, having undergone a calcination process at low temperatures, display higher thermal stability of around 300oC.
3. Health & Safety
As colorants, the production process for transparent iron oxide pigments conform to the requirements of Council of Europe AP (89)1 for polymers in contact with food; and EN71 Part 3 specification for use in toys at typical pigmentation levels; and with FDA Regulations 21 CFR Sections 73.1200, 73.2250, 175.300, 177.2600, 178.3297.

| Applications︰ | It is mainly used for automotive paints, coatings, plastics, printing inks, cosmetics, etc.
Directions:
In order to fully exhibit the high transparency and color strength, the Trans-oxide pigments must be dispersed completely. The forces of attraction between particles of small size are high and aggregates formed between the particles are difficult to fully disperse. Ideal dispersion depends on the manufacturing process and the equipment.
The first stage of a dispersion is to choose proper dispersants and solvent to wet the pigment surface to make it to be predispersion system and then choose proper equipment.
For relative low viscosity systems, a bead mill containing glass, steel or zirconia media is preferred, although ball mills or attritors may also be used . Where viscous systems are required, for example pastes or concentrates at high pigment loading, then a triple roll mill may be required.
After full dispersion, with the needle lengths of the particles under 5μm, the excellent properties of Trans-oxide pigments will be fully exhibited.
