Majority of Coatings Formulators Consider Reformulation to Address Rising TiO₂ Prices

Incorporate nano polymers which may increase the TiO2 dispersing capasity in the system

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.

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.

Dear Mr. Isaac, I would like to have more information about the extenders to be use in the formulation which can replace TiO2.

My opinion to replace partially by opacfying polymers & good extenders

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.

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 far as titan prices increased a lot a mix of some extenders will help to reduce titan cost and improve opacity and hiding power

using mix of some good extenders will help about a reduce of cost maximum 20 % as mentioned, in order to keep high opacity and hiding power

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 .

Dear Rahul:

One of the extenders we get very good results reducing the TiO2 by 20% is Portafill H5 from Sibelco.

Dear Pankaj,

Can you share the extender pigment you are talking about?
e-mail; vkalsani@ppg.com

Thanks,
Kalsani.

Dear Pankaj,
Could email details of the pigment you developed? Am interested. shalinder.dhillon@kagroupcomp.com

My view is no matter how many fillers you incorporate to make the costs come down, it certainly shall not solve the problems of formulators of solvent based paints.

The gloss levels tend to get affected badly with the use of these fillers. We have tried some of them, but to no use.
