Liquid Rubber Application - Needing help.

I'm trying to find a "liquid rubber-like material" that when heated or activated by a catalyst changes state from being a liquid (say syrup like or a gel) to a semi solid with a hardness of about 30 to 60 Shore A.

The application is for a down hole tool that will push this liquid from one piston chamber to another at around 110 to 250F (43-120degsC) and then set. The duration of cure and final set needs to be about 60 days but definitely more than 14 days.

It needs to withstand hydrocarbons and other chemicals. It would be a great benefit to be a single part mix.

Are there 1 part mixes out there?
Are there 2 part mixes?
And if so who supplies them and what are they called.

I'm getting a bit desperate as I have tried some potting compounds and they go brick hard. There's veru little moisture and no air down hole so using a bathrrom silicone sealant doesn't work either.

Any suggestions?
I'm posting this across forums as I think other industries may be able to help to.

A 2 pot polyurethane might work.

The slow cure time will be an issue. Talk to suppliers like Noveon, BASF and whatever Bayer Urethanes calls themselves now.

Silicones are also possible, but a grade to cure slowly and withstand hydrocarbons might be difficult. Talk to GE, Dow, and Wacker.
