No, apply to both mating surfaces and assemble. Needs to set for a few
hours for cure. Preheating to, no more 200° will accelerate the cure, but
do not go hotter than that. It can damage the bond, not to mention other
components. It's best to warm the joint up to temp. that you can still just
touch without burning yourself and that'll usually cure rapidly. The parts
should be reasonably clean and dry.

Lew,
Don't have to let it "dry", the product "cures" in the absence of air.

Assemble all Loctite-treated components while wet. The adhesive is
anaerobic; it sets in the absence of oxygen. There are other
compounds which are applied to threads and allowed to dry before
assembly, but the Loctite formulas sold for general use are not used
that way. Some set quite fast, so that the fastener needs to be taken
directly to its final torque as quickly as possible.

I'm sure the hardware store where you get this can advise you but this
does not seem to be an anaerobic adhesive according to the Loctite web
page:

On the other hand, I can't imagine what on a bicycle needs Loctite.
This stuff is usually for things that vibrate in the acoustic range
and are inadequately designed to prevent motion of the thread in
question. What's the application?

You are right.

When I rebuilt my Phil Wood hub/ratchet, I was instructed to use an
accelerant, by LocTite, on the toothed ring threads (to the hub).

I really don't think it matters very much w/ blue loctite. It's a
"friction enhancer" (my phrase). It doesn't dry very hard. It's not
supposed to. Unless the bolt has very strong force to disengage,
whether or not it's cured at first usage isn't really important. IMHO
Happy Holidays. John

to get the best bonding you'd be wise to let it dry before using...if in
doubt contact your local auto supply store in town.

I don't have a specific application in mind, I've just wondered
generally about how to use the stuff. I have used it myself on the
screws for attaching my racks and fender stays to the eyelets.

I have bought accessories that came with screws with the Loctite
already applied and "cured." For example, I think my aerobars had blue
Loctite pre-applied to the clamp screws. That's what got me to
wondering if it should cure before assembly. Perhaps it just doesn't
matter.

Hi,

Don't let it dry....I had this same thought once for some
reason...I was assembling a wheel for the first time and I
filled all the spoke nipples with loc-tite and let it dry.
Once it dried the treads became clogged with it and they
were useless. Loc-tite is basically like glue that gets hard
when it drys, it filled up the threads and became hard
as a rock. When used correctly though (when wet) loc-tite
makes a big difference in how long something stays tight.
I have seen what your talking about, where some bike parts
come prepped with it, so maybe if done in a certain way
it's OK.

Hope this helps, Alex

Hay, Jobst
Blue Loctite is useful on a bike any place that has a thin "nut" (that
presents a problem to achieve a high torque) such as the bolt that
secures the rear end the cage of a front derailleur.
I've also used it in the spring balance adjusting screws for cantilever
& V brakes, which were vibrating loose. The SPD cleats to my shoes.
Many other places that I can’t think of right now.
My rule is every threaded surface gets 1 of 3 things. Grease,
Antiseize, or Loctite.

One more thing about Loctite. It comes in tiny tubes, which last a long
time for me, & are rather expensive (~$8). My last tube of blue was
over 5 yrs old, when I noticed that it didn’t' seem to be curing. I
emailed Loctite asking the shelf life of an opened tube. Their response
was 1 yr. now I know that it’s more that 1yr, and its >5 yrs. my guess
3 to be safe, maybe 4yrs.
Best wishes for the Holidays, John

It won't dry (cure) prior to using, it's anerobic. Asking most auto
parts store clerks is better that asking a gorilla, but not much. Visit
Loctite's web site, or call their customer tech. service, or email.
Clerks will give more misinfo. than not.
Happy Holidays, John

Use them on fender bolts.

I thought Locktite accelerant was a cleaning product, like acetone. I use it to clean threads before applying Locktite.
