Any comments would be appreciated . it seems it can be used to infuse sandwich structures.
You need to buy a licence from them before you can get it or use it. Probably has to do with the patents involved. (owned by another company, by the way)
The same material is Airtech Dahltexx SP-2, which is more readily available.
But you also need the license from the EADS or Transtextil to use the Dahltexx SP2 in resin infusion.
Only if you tape it to the mould.
