I used it secure a bearing on a shaft it made locking compound work so fast you need to make sure it’s ready to go right into place it can set up so fast it stops moving all the way into place

1st off, this product IS NOT intended to clean greasy parts from the get go. It's merely use as a final clean before assembling your parts. Note: This product contains ACETONE and BUTANE and is highly flammable. Even though Acetone and Butane is not consider extremely toxic on certain web sites, I would consider as such. Meaning, you should be in a WELL ventilated area. I did my work outside and it still can take your breath away. I would highly recommend wearing gloves (e.g. nitrate) while working with it. It will dry the moisture out of your skin. Finally, wear a face shield for eye protection too.I hung my parts [bearing race] on a wire as I sprayed them down and let them dry. It remove any residual oil film on the race. I am using Loctite 660 to glue this bearing in place, due to spinning on its own. All of this is needed to insured that the glue bonds to both metal surfaces for the bearing race.I am well pleased how my project turn out and save me an expensive repair.

Expensive. Only option I could find to speed up curing in cold weather application of lock tite bolt retainer.

First, "what's inside":Acetone 67-64-1 60 - 100%2-Ethylhexanoic acid 149-57-5 0.1 - 1%Isobutane 75-28-5 10 - 30%Basically: cleaner, catalyst, and propellant.I had a knurled grain mill roller with a right-hand-threaded drive shaft that unfortunately I wanted to run in reverse, which mean the shaft would immediately unthread. I picked up some "permanent" Loctite and this "Activator" and after first cleaning both male and female threads to within an inch of their (or my) lives I applied the "Activator" to both parts, let them sit for an hour to ensure both parts were thoroughly dry, then applied the thread locker and screwed in the drive shaft and then let the assembly sit for 24 hours.Tested the mill with a full hopper of grain (~18 pounds) and it plowed through it all with zero issues. Knock on wood :)Cheers!

I have four non-tapered stainless steel pipe connections on a heating system storage tank. All attempts to seal the fittings with tape or pipe sealants failed until I primed the fittings with this product, and used Loctite thread sealant. One warning, after applying loctite thread sealer, the sealant begins setting within minutes, so if you prep the threads with this product, keep in mind that it quickly cures thread sealant.For Stainless steel pipe fittings, I highly recommend this product.

Works as expected

Did the trick for making a gasket on my JD Gator.

I used this product in an attempt to fix a loose pipe connection on my air compressor and seal the leak. Unfortunately, even after using this product to prep the surface the loctite sealant did not produce a hardened loctite seal and the pipe turns under pressure. I was hoping for a more permanent connection as a final outcome.
