Titanium Dioxide

This unique white pigment, for which no substitute can be foreseen in the short and medium term, is used in all areas of our lives thanks to its ability to protect materials from light and weather, its exceptional lightening power and its opaque properties. It absorbs UV rays, thus minimising system degradation, which prevents the appearance of brittleness, fading and cracking. It prolongs the useful life of the finished products in which it is incorporated.

TiO₂ is used everywhere in our society, and most of the white surfaces around us contain TiO₂ – in our homes, workplaces and public spaces. The most common applications are in building materials, paints, coatings and varnishes of all kinds, printing inks, plastic materials, adhesives, paper/stickers, rubber and plastics, ceramics, welding electrodes, food packaging, medicines, cosmetics and pharmaceuticals, coated textiles and fabrics, catalytic converters, automotive products, flooring, water treatment, etc.

The TiO₂ production process starts with the dissolution/smelting of black titanium ores (ilmenite and slag) in sulphuric acid, which is prepared in-house using clean sulphur combustion technology. The resulting product is purified in several steps, hydrolysed, washed, substances are added to direct the growth of the crystals into the desired structure, dried and calcined/heated at high temperature to form titanium dioxide, followed by surface treatment to obtain the final white pigment TiO₂. From the intermediates – interphase semi-products – we produce ultrafine i.e. nano titanium dioxide in the form of an aqueous suspension.

Pigment TiO₂ is a white pigment with a particle size between 200-350 nm. It is used to optimise the scattering of visible light and to achieve opacity. It protects materials from light and weathering, while offering exceptional lightening and coverability. Ultrafine TiO₂ has a particle size of <100 nm and as such loses its pigment properties and becomes transparent. The ultrafine grade of TiO₂ is suitable for completely different solutions and applications such as UV absorbers and photocatalysts.

Since 2005, we have been a member of the Titanium Dioxide Manufacturers Association (TDMA), an international association committed to responsible, safe and sustainable TiO₂ production, which is also our guiding principle for our production activities.

As a sustainable-conscious company we strive toward green technology, which at the same time meets legislation obligations. Therefore, we recently launched TMP FREE version also for following types of our TiO2: RC 813, RC 823, RC 833, that are designed to address the growing sustainability needs of coating producers. Cinkarna has prepared products without TMP (trimethylolpropane, CAS number: 77-99-6) in its development department, since TMP, as the most common additive for organic processing of titanium dioxide pigment, was classified as a dangerous substance some time ago.
