vapor deposition of urethane castings

Can any of you provide contacts for vapor depositing urethane? We have a
customer that would like to create an RF shield on their prototypes and we
believe that vapor deposition would be the best route. As an alternative,
has anyone had success using "filled urethanes" to create conductive
castings? We have tried using carbon black on several occasions with mixed
results. Typically, the amount of carbon black required to achieve any
conductivity is so high that the urethane/carbon mixture becomes a thick
sludge and will not flow into the molds.

Thanks for your help,
