Is anyone familiar with ballistic foam and how to acquire it in a non-hardened stage?

Question

I know that ballistic foam is used on aircraft wings, but I was wondering where can it be purchased either in a tube or container of some kind where it is not hard already?

Answer 1

I am not sure if ballistic foam is the same as the one used to seal gaps in conduits etc. which is available in any hardware shops , building material supplies. It comes usually in tubes in liquid form , when poured in gaps or any container , it expands and solidifies in few hours taking the shape of the container.However these are not certified to be used in any aircrafts. If are planning to use them in some aircraft them best bet is check aircraft part supplies.
