What doesn't Expanding Foam stick to ?

George,

Yes it was for ventilation originally when it was a cow barn, but my CNC machines don't fart as much as cows :)

I have this vision of a farmer having a cowshed like this, with the ventilation led to a vertical pipe in the corner and a permanent 'flare' as on an oil rig.

so expansion foam does NOT stick to cling film?

so is that the best way to stop it stic king to the mold framework?

here is a link to a home-made solution from previous Google link. this solution (pun intended) was mentioned elsewhere too.

Are you sure it sticks to anything? I thought the whole idea was to expand into voids, and seal up the hole. Brian

It is horribly sticky and sticks to almost anything. The low-expansion version is used as an adhesive - bonding plasterboard to walls and the like. Get it on your jeans and you'll forever have a pair of jeans with a patch of hardended foam on. Get it on your skin and, unless you use a solvent, it'll take days to get it off.

The solvent doesn't work once the foam is cured.

I believe it only comes off as the skin's surface is shed with it. Polythene is one of the least stickable materials on the planet, might be worth trying.
