Catalyst for superglue (Cyanoacylate) which takes about 3-60 seconds under normal conditions but if
if a catalyst is used, the glue sets in less than 2 seconds.
If you are gluing 2 surfaces together, put the glue on one part and spray the other part
put together and then the things should stick together.
You can use put the glue in cracks and spray it over and it will set right away
