Dear Paul,

what you say is true 3M does not produce anymore C4F10, but there are 2
companies in europe one in england and one in germany which stil lproduce
it, I have got prices from them per kg, I can send them around later.
In genrell the price is 100$ / kg or more, depending on how much you
order.

Cheers elke
