You might be wondering if you really need an activator with the FastCap 2P-10 Thick super glue. The short answer is: not necessarily, but it can really help. The manufacturer suggests using the glue on one surface and the activator on the other for the best results. This combo makes for a super strong bond in just about 10 seconds and fully hardens in about 30 seconds. If you skip the activator, you're still looking at a set time of about 10 to 20 seconds, and it cures completely in roughly 5 minutes.
Our research shows that this glue is pretty popular, especially in areas like woodworking and crafts, because it sets quickly and fills gaps really well. It's great for all sorts of materials—wood, metal, plastics, ceramics, you name it.
While the glue is strong on its own, the activator is a good addition for tougher projects where you need extra strength. And if you're using it for gap-filling, make sure you get the thick version. Having clean and slightly rough surfaces can also help the glue work better.
In short, the activator makes things faster and stronger, but the glue itself is still pretty versatile. Just remember that doing some prep, like cleaning surfaces, generally leads to a better finish.
