Hi guys,

As Matt was saying, for polypropylene sheet and PTFE you dont need any release agent, as the epoxy will not stick to it at all.

Are you planning to make flat sheets of material? Then your definitely best with a sheet of glass, coated with easy-lease as a mould. It can be re-used indefinitely, unlike the other materials which will become scratched quite quickly which will be visible in your surface finish.

cheers

Hi Mani,

Like Baja says, no release agent at all for polypropylene. PVC would need Easy-Lease (do a test first to make sure it works and that the solvent doesn't upset the PVC), Perspex is a strange one and MUST be tested first because from one brand to the next you will get different results.

Only consider any of these alternatives if glass is not an option (i.e. if the mould is not flat) otherwise go with glass every time.
