Titanium Dioxide

Since 1973, Cinkarna has been producing micronized rutile pigment TiO2  using the sulphate process under our ''RC'' label, which is inorganically and organically surface-treated depending on the application, further improving the basic properties of the product.

About titanium dioxide

Titanium dioxide (TiO2) is a white inorganic solid substance. It is produced worldwide in two main commercial forms. The older and quantitatively more essential is pigment production, while the ultrafine or nano form of TiO2 is gaining importance with the development of modern technologies.

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.

 

 

Sustainability

Towards a brighter future

Due to its outstanding properties, TiO2 offers sustainable solutions in a wide range of applications, both in industry and in everyday life. Due to its high refractive index (ability to reflect light), it reduces solar heating of surfaces and consequently reduces energy consumption for cooling living spaces, while at the same time, due to its exceptional light reflecting properties, it reduces material consumption and, consequently, has an impact on waste reduction.

Energy savings

The use of lighter colours for interior applications creates an effect of openness and spaciousness. The strong glow characteristic of lighter colours reduces the energy consumption needed to illuminate interior spaces compared to darker colours. In exterior applications, the coolness of TiO2-coated surfaces also creates energy savings in warm and tropical areas, as the light reflectivity reduces the need for air conditioning.

Waste reduction

The value that TiO2 adds to products can very often have environmental benefits. TiO2 is a strong opacifier and therefore allows thinner coatings in applications and therefore a more efficient use of this source, resulting in less waste.

Carbon footprint and Life Cycle Assessment (LCA) of TiO2 pigments

We have carried out a life cycle analysis and carbon footprinting for our products together with other TDMA manufacturers. Find out more at the following link:  https://tdma.info/life-cycle-inventory
