Hi.

Im looking to remould the plug from my 2 part mould after destroying the original using this casting resin. Problem is (unless im blind) I cant see where it says how much 2kg will fill in volume ? Also it possible to thicken the resin during application as pretty sure if the viscosity is too low it will just flow between the gaps. Finally, should I wax and release agent the moulds before casting ?

Thanks

You will need to seal the join line so it can't leak out. Increasing the viscosity won't stop that unless you make it like custard in which case you might loose detail on the part.

You will need to use a release agent to ensure the part releases from the mould.

The density is 1.06g/cm3  thus 2kg of resin will occupy 1887cm3 or 1.887 litres of volume.
