Title: Question on threadlocker.
Post by: gauravag on January 20, 2010, 02:56:24 PM
Hello,
On my recent Singapore visit i bought 2 threadlockers from Singahobby :
http://shop.singahobby.com/?q=node/20188 - Red
http://shop.singahobby.com/?q=node/20187 - Blue

Now, while assembling/working on my Heli, can I use these or do i need to get the specific T22 ? The issue i am concerned is that they may be a little stronger than whats needed on the miniTitan / Raprot 50 ( throughout the manual, there are instances where they have directed to use red/blue threadlockers ) and i may end up having a hard time during dis-assembly later.
Or are these OK, and i just ensure only a little bit is used ?

I have similar ones from another brand, and use the BLUE ("removable") one for 99% to 100% on any heli build.  The rare 1% where you use the "permanent" RED ones are when you are 100% sure that you would NEVER want to remove it (for example, to connect the 3 ball-ends to the swash plate itself).

Using the red one else where can cause serious grief, as reported by Rajesh/RotorZone here :

The whole thread should be of interest to you.

Thanks, i read the thread the other day and that is why was concerned about the usage of this product. I know i will need to open many of the fasteners at some point in case of a crash so need to be careful. Will use the blue one and with care.

It wasn't red. It was blue anabond one that caused the grief.

Blue for removable and red for permanent is a standard that is being adopted by many thread-lock makers, but not all. Over application of blue itself may cause such issues.

It is critical that only the last 2 to 3 threads alone are coated with the glue initially for optimum performance.

As suggested by Adarsh(http://www.adarsh007.com/index.html) the Loctite 222 is better than Anabond blue. It is Low strenght Thread locker for smaller screws. The MRP for 50 ml is 416, But I got it for a street price of 350 bucks. This will last longer than the 2 years expiry date.
