Questions & Answers

Would this be useful for priming barrel threads with certain coatings before using threadlock to mount various muzzle devices?

No, there's acetone in there. It'll get rid of the bluing.

What makes this different from 19269/7649? 271 would benefit from the use of a primer. TY. ?

7649 type of primer, which is N, and 19269 size and type of container, which is 1. Glass bottle with a capacity of 75 fl oz

Is it necessary to use a primer when only the surface of the metal is inactive, such as in moly steel and aluminum?

Because Loctite anaerobic products cure in the absence of oxygen as well as the presence of active metal ions, it's common to use a primer on the surface of inactive metals like the ones mentioned to achieve a cure time comparable to that of an active metal like steel. However, the primer may not always be necessary, so it's always a good idea to test it out first.

Selected User Reviews For Loctite 494147 Klean N' Prime Anaerobic Primer Activator Can, 4.5-oz.

This is very effective, but be cautious

5/5

It's a fantastic product that does exactly what it says on the tin. However, it contains some dangerous chemicals, so use caution. When using, use a P100 respirator and work in a well-ventilated area (don't make the same mistake I did!).

Working with aluminum and stainless steel necessitates the use of this product

5/5

I was working on an old jet ski, and no matter what color thread lock I used or how well I cleaned the parts with acetone, I couldn't get the stainless steel bolts to stay in the aluminum engine. Fortunately, I came across this product before losing hope. Loctite thread locker, it appears, requires iron to activate and form a strong bond. My bolts would always shake out because stainless and aluminum are both non-active metals. I had a fantastic season on the water after I was able to use this primer and allow the bolts to cure.

My other Loctite Sealants have a faster cure time

5/5

This worked perfectly with Loctite 515 and Loctite 592. br>I used Acetone to clean the surface before spritzing it with this. Allow a few minutes for it to dry before applying the sealant. br>br>On non-porous surfaces like aluminum, this will activate the sealant. It'll also speed up the healing process. br> br>br>I recommend looking up the online data sheets for whatever Loctite product you're using because they have a lot of useful information about cure times and other things.
