It is a catalyst that cures it near instantly. Try it on a couple of scraps of something. Dust one scrap with baking soda, apply the glue, dust the top of the glue with a pinch of baking soda, smoosh the objects together.
What oozes out, dust that with a pinch of baking soda. after you do this you will see why I recommend it.
I go a step further and do one more application of super glue then dust that with baking soda to fortify the connection. Not sure that I need to but it makes me feel better about the fastening while the epoxy cures.
