Dissolving the PU foam on a solvent ?

Group: Forum Members Posts: 17, Visits: 193	Hi I was wondering if it was possible to dissolve the PU 80 low density model board in some solvents after having laminated a CF cloth around it ? The idea would be to - cut the foam to the target shape - apply the epoxy/CF cloth - dip the hole thing in a jar of acetone / other solvent Thanks for your help ! P.

Group: Forum Members Posts: 17, Visits: 193	Are you sure you can dissolve an epoxy like that ? I am trying to design a case for my phone (small project) and I thought an easy way to have the right shape would be using the PU foam cut to size, and dissolve it after the epoxy is cured. The other way that I thought is to make a wooden model of the phone (e.g. balsa wood) and wrap it on a PP sheet. Once the epoxy is fully set, I can pull the wood out, then peel the PP sheet off (and no release agent required). Thanks for your answer Baja_Patient !!! P.
