Nano Technology vs Zinc Phosphating [India] 

April 16, 2008

Dear vSir

which is better technology in Nano or Tri-cation Zn Phosphating.

How much cost effective, quality and costing.

Please let me know as everbody is talking about Nano Technology but nobody seems to know what exatly it means.

Lot of people says it is based on solvents and hence does not produce sludge at all is that mean that it is not a comnversion coating.

Lot of International companies are claiming that Nano is cheaper in costing even though the over all prices are higher aroung 5-6 times more that Zn phosphating and low maintenance of the bath etc.

Please explain.

Ed. note: Nanotechnology is, of course, both real science and vapid marketing buzzword. We ask that any replies speak in science terms, and must discard any that simply promote proprietary products.

Dear Amitabh

Till now in India no body is sure about this new system, as the SST is quite low not even 500 hours.

Since this is a platform to discuss new things I think we should ask our counter parts in Europe or USA to throw more light on this matter because many International companies are trying to sell Nano Tech based products in Indian market.
