  • Background and overview

    Globally,     Iron Oxide is the second largest inorganic pigment after Titanium Dioxide and the first largest color inorganic pigment. Iron oxide pigments mainly include iron oxide red, yellow, black and brown with iron oxide as the basic material. Iron oxide yellow, also known as hydroxyl iron oxide (FeOOH), will be dehydrated and decomposed into red at about 177 ℃, so the application of ordinary iron yellow pigment in high-temperature occasions such as plastic processing and baking coatings is limited. Iron oxide yellow pigment can improve its temperature resistance through surface coating, so as to expand the application field of iron oxide yellow pigment.

    The chemical formula of iron oxide yellow (also known as hydroxyl iron) is α- Fe2O3 · H2O or α- FeOOH, with needle like structure and yellow powder, is a kind of particle size less than 0.1 μ m. Iron series pigment with good dispersibility in transparent medium has strong coloring power, high covering power, insoluble in alkali and slightly soluble in ACID. Synthetic iron oxide yellow has the characteristics of light resistance, good dispersion, non-toxic, tasteless and difficult to be absorbed by human body. It is widely used in coatings, plastics, ink and pharmaceutical industry.

    Physical and chemical properties and structure

    1. Iron oxide yellow pigment has acid and alkali resistance, resistance to general weak and dilute acids, and is very stable in alkaline solution of any concentration.

    2. Iron oxide yellow pigment has certain light resistance, heat resistance and weather resistance. Its coating color is durable and can keep the coating from being damaged in light. Iron oxide yellow pigment is stable in a certain temperature range, but beyond the limit temperature, its color begins to change, and the degree of change is more significant with the increase of temperature. Iron oxide yellow pigment is not affected by cold, heat, dry and wet weather conditions.

    3. Iron oxide yellow pigment is very stable in any ambient atmosphere (such as gases containing H 2S, Co, so 2, HCl, no, etc.). And resistant to pollution, water, oil and solvent penetration, insoluble in water, mineral oil or vegetable oil.

    4. Iron oxide yellow pigment has strong coloring power and high hiding power. With the decrease of pigment particle size, its coloring power is stronger.

    application

    Nano iron oxide yellow has the characteristics of acid resistance, alkali resistance, non toxicity and low price. It is widely used in coatings, plastics and rubber. The particle size of nano iron yellow is less than 100 nm, which makes it have some unique characteristics. When light shines on its surface, transmission and diffraction will occur, showing transparent yellow, and can strongly absorb ultraviolet rays, Therefore, it can be used as a functional pigment for the surface paint of high-grade cars, precision instruments, bicycles, motorcycles, cosmetics, food, drugs and other coloring additives.

  • In vitro, in the hemocytes of the marine mussel Mytilus hemocytes, suspension of TiO2 NPs (Degussa P25, 10 μg/ml) stimulated immune and inflammatory responses, such as lysozyme release, oxidative burst and nitric oxide production. Vevers and Jha demonstrated the intrinsic genotoxic and cytotoxic potential of TiO2 NPs on a fish-cell line derived from rainbow-trout gonadal tissue (RTG-2 cells) after 24 h of exposure to 50 μg/ml. Reeves et al. demonstrated a significant increase in the level of oxidative DNA damage in goldfish cells, and suggested that damage could not repaired by DNA repair mechanisms. Another suggestion from the mentioned study was that hydroxyl radicals are generated also in the absence of UV light. It has been shown that fish cells are generally more susceptible to toxic/oxidative injury than mammalian cells.

  • Application:
    1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.

    2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.

    3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.

    4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
  • In conclusion, the choice of a lithopone B301 supplier is a critical decision for any business involved in the pigment industry. Suppliers who prioritize quality, capacity, innovation, customer service, and ethical practices are the ones that truly stand out. By partnering with such suppliers, businesses can ensure a steady supply of high-quality pigment, thereby fostering growth and success in their respective markets.

  • 3. Regulatory Compliance It is crucial for suppliers to adhere to industry regulations, especially in sectors like food, pharmaceuticals, and cosmetics. Reliable suppliers will ensure their products meet relevant regulatory standards, providing proper documentation and certifications.


  • The quality of Chinese lithopone is also influenced by the country's robust regulatory frameworks. Strict guidelines govern the pigment's production, from the synthesis process to the final packaging. These regulations ensure that every step aligns with both national and international standards for quality and safety.
  • One of the key products offered by internal wall coating suppliers is damp-proof coatings. Damp can be a serious issue in buildings, leading to a range of problems such as mold growth and structural damage. Damp-proof coatings provide a barrier against moisture, preventing it from seeping into the walls and causing damage. These coatings are essential for maintaining the integrity of the building and ensuring the health and safety of its occupants.

  • Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO2) as a food additive. Food-grade TiO2 is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO2 has long been considered safe in Canada and in other countries when eaten as part of the diet.
