VC Series Threadlockers

Unlike a traditional threadlocker which attempts to fix a fastener solidly in place; VC-3 works on the principle of vibration damping. VC-3 essentially isolates the fastener from the vibration of the assembly, absorbing any intense shock and vibration which keeps the fastener from rotating. However, when you try to remove a fastener coated with VC-3 with continual torque in a singe direction, because of VC-3′s viscous flow properties, it will eventually rotate out. But this action is not representative of vibration in a real use situation where the direction and velocity is of a more random pattern.
The solvent in VC-3 is MEK, VC-4 contains Ethyl Acetate, VC-5 contains MPK, and VC-6 contains Dimethyl carbonate.
Vibra-Tite VC-3 passes NASA spec sp-r-0022a for outgassing properties.
The drying time of VC-3 varies depending on how much material was used. If coating a large fastener with deep threads, it may be necessary for the part to dry up to 30 minutes before use. We recommend at least 10 minutes for most parts.
Increased air flow will help to decrease drying time. We do not recommend the use of a heat source as the solvent in VC-3 (MEK) is flammable.
MEK or some paint thinners which contain MEK are best for cleaning up spilled or excess VC-3. Be sure to use the proper safety equipment such as gloves, mask, goggles and ventilation.
Yes. The solvent in VC-3 will re-liquify and adhere to the existing material on the fastener. After drying for 10-30 minutes the fastener is once again ready for use.
VC-3 is extremely versatile. It can be used in applications ranging from automotivemotorcyclehome repairsportingfirearmsR/C, and more.
There are two ways to approach the use of VC-3 when discussing plastic compatibility. If you apply VC-3 directly to a plastic fastener, there is a limited selection of substrates which are compatible. Please review the table here as a start, and be sure to test first.  The second way to use VC-3 is when you are installing a metal fastener into plastic. Because VC-3 must be dried first, all the solvent will have evaporated and you should be left with an inert plastic threadlocker.  You can then install that fastener into practically any type of plastic assembly.
