Hi Boris,

Thanks for the information. This sounds interesting, as does using Teflon AF
described by Kevin Tsao. 112-115deg is right in in ball park of contact angles
I am after.

Is your method proprietary? If not, can it be adapted using standard (and
simple if possible!) lab methods? Is it possible you could forward some further
details or alternatively point me in the right direction?

Many thanks and best regards,

Paul
