I have a resin piece I want to mold, but I treated it with superglue an hour ago. The superglue is dry to the touch.

In my experience superglue needs an overnight cure, otherwise it can inhibit the silicone mold rubber.

I know ambient moisture cures superglue. If I submerge this item for a minute, will the water neutralize any remaining cure-inhibiting compounds? If not, is there any kind of solution outside of waiting? I tried heat earlier, and that didn't work.

I'm curious what you have experienced with CA glues and silicone?

I have never had any issues, and I use CA/super glue all the time when I'm setting up my molds.
I use it to attach parts to fill & vent sprues - often pouring in the silicone within minutes of gluing the parts in place.
Sulphor and cold temps are the most common inhibitors I've come across.

Perhaps it is the CA accelerator? What brands of CA and silicone do you use?

I have only used Super Glue brand CA, and sometimes I'll notice tacky (casting in Mold Star 16) sections after demolding. I talked to the rep at Reynolds Advanced Materials and he indicated this was normal for CA glue.

I've never had any problems with cure issues with silicone and CA. That's a first I've ever heard of it. You let it cure naturally or do you use an accelerant?
