What is in cayo accelerator?

Odd. My pint of accelerator is over ten years old, working quite well—but I keep it TIGHTLY closed. It sounds to me as if yours lost the solvent carrier. Amine compounds do have a tendency to clump under the right conditions (which may be how life got started on this rock, but that's another digression…

I would not keep the stuff in the fridge. Just keep it tightly closed and in a cool, dark location.

Gip (Styrene) has told us that the development of CA as a surgical adhesive (as I, too, had read) is partially an urban legend. He says is was originally developed as an optical adhesive, and then later adapted to surgical use. Since he's in a medical field, I give his history more credibility.

Okay, I guess Bill shot down the urban legend, and Gip brought up the methacrylate. I stand corrected…gotta buy more white-out…
