Do I need a release agent?

This is probably a silly question, but to use the unimould system on a epoxy coating resin finished plug, do I need to use a release agent before putting down the first tooling coat?

Thanks,
James

Hi Dennis,

Mmmm, yes, the sequence if you use Easy-Lease and wax together is very importantly  Easy-Lease first, wax second. If you do it the other way round the Easy-Lease will effectively remove the wax but at the same time contaminate the Easy-Lease so you've got neather a was or a chemical release agent barrier. In the correct order there is no reason why the release shouldn't be perfect, leaving both the pattern and the mould as they were.
