Unfortunately we do not stock any clear epoxy gelcoats at all. Could the mould top be cast from a clear epoxy resin instead?  We do have clear casting epoxy resins suitable for a variety of casting thickness.  However I would look at our GlassCast range of epoxy casting resins, particularly our GlassCast 50 Clear Epoxy Casting Resin which is great for thicker castings over 10mm thick.  Its HDT is around 50C so it would only work for room temperature curing really.

Dear Easycomposites Team!

I need your advice beceause I would build a mould for RTM Lite process and upper mould half must "see trough" for checking as the resin flows.
I'm looking for clear Epoxy Tooling Gelcoat without pigment.
Thank you for your help!

Best Regards
Viktor
