Threadlocker and Messy Drips

One of the challenges in bonding applications is keeping the adhesive to stay within bonding point or area. A little mistake and the adhesive can cause serious problem. A threadlocker applied on a cap used to seal bearings can drip into the bearing components and prevent it from rotating. So the question is how do you stop messy drips?

The most obvious solution is to apply only the right amount so that there is no or very little excess that can be squeezed out when the bonding surfaces are pressed to each other. However, things can get a bit tricky when dealing with threaded surfaces.

The gap between the internal and external threads have to be filled with the threadlocker. In order for it to be properly filled in, applying in excess becomes the normal procedure which brings us back to the previous problem. Moreover, you can't really be certain if the excess threadlocker had spilled inside or not since there is no way to see in.



There are new threadlocking products designed to address this problem. These new products come in gel form which is effective in filling gaps while preventing drips. The excess product that is squeezed out when closing the threaded fasteners like screw caps will stay in its place instead of going everywhere. With these types of threadlockers, you don't have to worry about not moving the assembled components while waiting for it to cure completely.  You can save yourself from the trouble and cost of failed assembly due to messy drips.
