How non-toxic is CA glue? Answered

Hi gang, I know CA glue (Krazy glue, Cyanoacrylate) is solvent based, and inhaling the solvent is bad for you, but how safe is it after the glue cures? As I understand it, after curing the glue is basically a plastic.  Can I use it in a baby's crib (Assuming it's allowed to cure)? Thanks!

How to (properly) glue a SMD leds to (slightly flexible) plastic?

Hi people or robots, For a project of mine I need to glue SMD leds to a transparant piece of plastic. the LEDs need to be glued face down on the plastic so the soldering contacts are facing up. I've already tried super glue (CA glue) but this didn't hold, the LEDs would pop of when the plastic was flexed a bit. What would you (the awesome instructables community) recommend? I've ordered some two part clear epoxy to give that a try, would that work?

Cyanoacrylate accelerators?

I just read about these substances that are usually sold in mini spray bottles or aerosol cans.  They are supposed to be very useful when you apply a cyanoacrylate (CA) glue (aka superglue, etc.) over a somewhat large, flat surface, as they enhance the alkaline conditions to speed up the polymerization of the CA.     Given this information, does anybody know if a CA accelerator can be made from scratch by regular high pH household materials, like ammonia or sodium hydroxide?  If so, what concentration do you think would work?
