I know Michael has much more experience with 325 especially since he recommended that I use it originally.  I used it on my first folder that didn't have a rear bolster and the lack of that 2nd bolster was the reason he said to use it and I agree it is perfect for those situations.  The setup time for me was about 5 seconds max but probably closer to 3 secs and it was locked in.  I think, since it uses a catalyst that if you were to let the catalyst dry more than I did the working time would be higher.  When I sprayed the catalyst on the scales I let then sit for about a minute before joining but this left the catalyst still a bit wet and may have caused my quick set time.

I will say that once the 325 "grabs" it is game over for moving the scale so you have to move fast and get it right.  The good news is if you maintain everything oil free (I wear nitrile gloves) you should never have a scale failure.  I have done over 2,800 knives with this adhesive and ZERO have come back to be re-attached.  You need to discard it once you get 3 months past the expiration date.   I have had a few in shop failures and every time it was with expired 325.   zoro.com has been reliable for shipping non-expired 325.  Don't even think about Ebay - I did early on and at least 70% of the bottles I was shipped were expired 325 or the expiration date section of the label was cut off.

I googled Loctite 325 and it says: Single component with 24 hr. cure time.  What is this catalyst that you use?  And does the 325 work all by itself without failures?

Without going out to the garage to check I think the kicker was 7075 and comes in a small spray can.

Loctite 325 Speedbonder structural adhesive is a high temperature, two step acrylic, no mixing required transparent brown adhesive. Loctite 325 is solvent resistant and, when used in conjunction with Loctite Primer 7075, forms flexible bonds on gaps up to 0.04 Inch.
