Solvent Resistant Sealers - Know of any good ones?
I'd like to ask for a little bit of assistance from the knowledge bank out there. We are engaging in a little testing for a customer and need some assistance in identifying a few more materials to test.

The most problematic exposure for the application appears to be immersion in 99 degree C ethyl acetate (under pressure).

The temp./chemical combination will pull most organic sealers that I am aware of apart very quickly. Are there any inorganic sealers out there that may be worth investigating for the application? While it is a field application even materials that require a heat cure are being considered at this time. Any and all suggestions appreciated.

That sounds like a challenge. I will have to have a think, I can only suggest trying PTFE (will require high temperature curing) off the top of my head at this moment Rolleyes

We are going to do some testing with some sodium silicate materials (similar to those used for sealing castings). PTFE would solve the chemical issue, but I would be concerned about erosion and process contamination with a sealer that so readily abrades. This is an aggitated reactor vessel and the process does contain a substantial volume of solids. (probably should have mentioned that in the original post)
