Majority of Coatings Formulators Consider Reformulation to Address Rising TiO2 Prices
- Jul 1, 2011
Increasing TiO2 prices have been a significant concern for coatings companies since the rebound after the crisis. Since 2010 TiO2 prices have increased significantly in all regions of the world and for example, have moved to 2,4 €/kg (3,4 USD/kg) in Europe in February 2011 (Source: ICIS).

Embark on thorough research and improvement of extenders and opaque polymers in addition to trying different extender combinations as well as trying to develop computer technology to come up with cost effective titanium/extender combinations. The same approach can be used to titanium/ nano polymers combination.
New Extenders for reduce of TiO2 content - Jul 14, 2011
posted by Isaac Goldfarb, R&D - Applied/ Formulation/ Product development at Colori-Dקךלםך
The matket today because of TiO2 price increase offer a lot of new extenders in order to reduce about 20% the TiO2 content without changing the properties of the paint and the reduce of wet opacity is practically insignificant for the end user.
If some one want to know some of them please contact me.

Extenders for Tio2 are equipment and application specific. The theory is mostly acceptable but only if the process equipment is capable and can fully disperse. Also only applications such as thin film are where the advantages can be gained or with translucient materials by means of diffusion. Thin film applications already most likely utilise these materials anway as this idea has been around for decades. When I was developing masterbatch and liquid colourants obtaining the maximum efficient level of TiO2 was always the most ecconomical way, too much TiO2 is just a waste. Extenders can add to costs in other ways such as development time and procurement and can be false economy.

we have done a lot a work using extender to reduce the use of TiO2, including the so called plastic pigment. We have also been testing new sources of TiO2 but we have not been lucky most of then do not fill our requeriments.
Some pressure on TiO2 can be relieved Using a special TiO2 extender - Jul 25, 2011

We have experimented and developed a value added extender Pigment .
It is a high purity, brilliant white, precisely engineered, hybridized, inorganic extender, with very fine and controlled PSD (Particle Size Distribution).It provides an excellent TiO2 extension possibilities in Water based, high PVC, matt emulsion paints only. It can replace sizeable amount ( even 50% and more) of TiO2-R in properly designed Formulations.
It allows to formulate equivalent dry opacity (after film dries), durability, excellent pigment packing in dry film-improving scrub value , cost reduction possibilities.

As good as the suggestion on cost reduction of TIO2 are,by incorporating good extenders.Application of the product plays a big role in the final analysis of the cost effectiveness .Where the film weight is high,there may not be any gain .
