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 use of food-safe titanium dioxide in manufacturing poses both promises and perils. While it is an effective and affordable whitening agent, there are concerns regarding its potential health risks when consumed in large quantities over a long period of time. To address these concerns, it is important for manufacturers to take steps to ensure the safe use of TiO2 in their products, and for regulatory agencies to establish stronger guidelines and regulations regarding its use.
