CA Glue accelerator info
Here is a bit of info you could find usefull.. It's not my words by the way
Accelerators
Besides water, cyanoacrylate polymerises also in presence of alcohol and basic compounds (including weak amines). The latter can be used to produce a superglue “kicker” – a compound which triggers quick polymerisation of the glue.
Baking soda is one well-known substance with this effect. If you apply a layer of superglue to a seam and gently pour baking soda over it, the glue will cure very quickly. It makes for most effective filler for smaller jobs, and the baking soda results in a slightly rough surface which is good for sanding.
The great advantage of using superglue as filler is the total absence of shrinking which plagues most solvent-based fillers on the market.
There are also commercially available liquid accelerators, but as baking soda has the same effect, I personally prefer it over another harmful chemical in my workshop.
Like water, the accelerator also affects the reaction through surface contact, so it will be much less effective on thick layers of glue. When filling larger recesses with superglue, it is therefore advisable to build up the volume in several thin layers rather than applying a large volume of glue at once.
With these precautions (i.e. working with small amounts at a time), CA can also be used for moulding smaller detail parts, which I have tried with success.
