I haven't kept up with "accelerator" development in the last 2 - 3 years, but going back before that, I do remembers several articles and posts here that discussed the different kinds of "accelerants". Here are two that I remember and there were discussions on these:
Water is a mild acclerant and some "mists" contain water as part of their ingrediant.
Acetone is similar. I remember the shock from several here when someone listed Acetone as one of the ingrediants in one accelerator, especially since Acetone disolves CA.
With other ingrediants as accelerant, and with CA from different mfg'ers with their own blend, it would seem likely that they forumlated the accelerant to be compatible with their CA formulation. IMO, most commercial CA's are close to the same but some are different and specialty CAs probably have a different composition, requireing different Accelerator composition.
I have not had any CA cracking but I know that it does. Experimenting cross brands between CA and accelerant increase the potential for problems, but that doesn't mean that there will be problems. The user will just have to accept the responsibility if something does go wrong. It is "experimentation" that drives pen making forward!
