How to dissolve foam?

[starbuckcylon]

I have a resin rotocaste part that I foam filled but now I'd like to removed the foam. It’S a hard foam from Smooth On. is there anything I can shoot on it to desolve and soften it up?

Thanks,

Jim

Can't say how well it will work with Smooth on's urethane foam, but try some acetone on it... Or a propane torch...

Well, acetone will dissolve styrofoam very easily. Urethane foam is designed to be solvent resistant. I think you're stuck. You can drill it out and do some sanding, but I think that's about it.

Oh and one more thing. Come on! Why white letters that I have to highlight to read?

Gasoline?

gasoline and a match should do it.

Look, the stuff is toxic in its original liquid form - I think using a chemical to dissolve the SOLID stuff is asking for a pile o' trouble.

Laquer thinner depending on type of foam.

I tried various chemicals to disolve some recently. None worked. I wound up using a cutting bit with a power drill to cut/hack the stuff out. Once I did that I used the bit, a Dremel, or sanded by hand, any surfaces that I needed the foam to be completely removed from. Really, the only problem I had was when I would run into areas where the foam had not been mixed evenly and was hard instead of porous.

Good luck with whatever solution you apply!
