Can superglue (cyanoacrylite) be thinned with acetone and still harden? I'm looking for something with an extremely low viscosity to use as a binder for cold casting iron oxide with very fine detail (it's to make a slotted winding core for an electric motor with $\pu{1mm}$ slots). My plan is to thin out the superglue with acetone enough to make a slurry for pouring in the mold - possibly also mix in some water just before the pour to speed the setting process.

My question will superglue still harden if it has been thinned with acetone or would this destroy whatever properties that make superglue such a useful substance once it hardens? It's stated in many places on the internet that acetone works as a solvent for CA glue but this is only ever mentioned in the context of dissolving the end result.
As you can see from the reaction of cyanoacrylate from Wikipedia, the carbonyl ($\ce{C=O}$) groups do not react with the cyano acrylate which means that acetone should not react with your super glue.



That does not mean though that any water present in the acetone won't. So you should make sure your acetone is dry. But even if the super glue does cure, it is dissolved in acetone and will still act as a binder for the Iron oxide.
