you need a chemist
Chem Engineers push chemicals around they are chemical plumbers, Chemists (the industrial kind) makes it all happen, they are chemical chefs ;-) I used to be the later.
So what has occurred is exactly as walt alluded to.
Its most likely reacted a little quicker. A couple things will do this and they are all based on the energy of activation. So heat will make it go quicker because there is more energy to overcome the energy of activation and the catalyst lowers the energy of activation.
Either way it is just doing what it normally does at a higher rate.
The repercussions of this are that it will stay plastic for less time. As you know when you tick the two surfaces together there is a time when proseal is still a completely plastic (moveable) fluid. Then it begins to cure (cross-link). When reacting faster you have less plastic time and so if you?re going to move it in position you need to be accurate with your actions.
Issues with this? Once it has begun to cure, if you move it, you don't have as much "give" in it. ie it will tear or break. Before curing there is nothing to tear, it?s not cross-linked, so it just flows.
However like Walt said, if you made it up, put it on, then stuck your surfaces together, and leave it then it?s no different to normal.
