epoxy resin preventing from sticking.

[speelwerkParticipant @speelwerk]

Would a silicone spray prevent a metal (silver) hinge from sticking to a casting epoxy resin, or should I use something else? Niko.

There are a few things available..

Non stick epoxy

Silicone may interfere wit the curing of the epoxy. Paraffin wax (solid at room temperature) as used for candles and home canning can be used as a "mould release" coating, and will not interfere with the epoxy cure, or bleed out of the hinge later!

If you melt some wax in a tin over a pan of hot water and dip / air cool the hinge twice you will get a thin but complete coating. Good luck with it!

PVA mould release just paint on a couple of coats.

Second that – works a treat – just comes in inconveniently large quantities ( 25liters) in my part of the world!

Any carnauba based wax works very well – used as epoxy lamination release on molds the world over..wipe it on, let it almost dry and buff it a bit – do a second coat and thats it.

If you can get hold of Meguiars Mirror Glaze wax – that would be perfect.

*1 for Meguiars Mirror Glaze 8 mould release. Great stuff!

Where suitable,I've used brown parcel tape, the very thin stuff, as "non-stick" for resins. Works well, one big advantage being that there's usually a roll of it conveniently available in the house.

Thanks all! Lots of possibilities, I like the paraffin one. Niko.

I use DEVCON for bedding rifle actions into stocks. In order to ensure that I can get the two items apart after curing I first wipe the barreled action down with alcohol then brush all over with boot polish, leave 5 mins to harden, polish off and repeat. Never had a problem seperating two very expensive items.
