This document description the application proceedures to safely apply the ED-7100 carbon paste.
Using  ED-7100 carbon paste is to avoid the sparks in TGEM-foil when the voltage is higher than 4900 V, in addition to use the paste for painting a neutron sensitive layer on the surface of the TGEM-foil after being mixed with Thorium-232.

Hi Haitham,
 
  I looked into screen printing equipment and found a manufacture by the name of M&R Printing,
 
  if you go on the internet and type that in you can look to see if they have something that would fit.
 
Other than that I know some people have used equipment.  With regards to the SW100 we have a material that is the same which is   
 
  our Additive T.  If you need a pint of that testing let me know.
 
Hope this helps

I looked at the website related to printing equipments, they have many choices but I still need to discuss more about what do we need exactly.
 
 
I sent to him to send us additive T instead of SW100.

Purpose

This document description the application proceedures to safely apply the ED-7100 carbon paste. File:ED7100 Series paste.pdf

Requirements for safe handling

Before opening the paste please read the ED-7100 Safety Data Sheet located at

http://wiki.iac.isu.edu/index.php/File:ED7100_OSHA_MSDS.pdf

Be sure that the following are available:

Ventilation

An externally venting fume hood is recommended when working with this paste or a work area with very good ventilation.

Poor Ventilation area

Wear a well fitted NIOSH approved or industrial type canister mask.
