VC Series threadlockers are designed to be adjusted, removed, and reused. They utilize a blend of acrylic resins in a solvent base, which are applied to fasteners and dried first, then installed into mating part.
The primary difference between all these products is the solvent carrier. VC-3 is Methyl Ethyl Ketone, VC-4 is Ethyl Acetate, VC-5 is Methyl Propyl Ketone, and VC-6 is Dimethyl Carbonate. Each of these solvents reacts differently when in contact with specific plastics. If you have a metal fastener; whether installed into a mating metal or plastic part, we recommend VC-3. Apply VC-3 to the metal fastener then allow it to fully dry. The MEK solvent should have evaporated leaving behind an inert polymer which will not react with other materials. You can then install the metal fastener into the plastic mating part.
However if you plan to use these threadlockers directly on a plastic part, please consult the following table as a reference and be sure to TEST FIRST before using in production.

HotVibra-Tite VC-3 Threadmate
Vibra-Tite VC-3 Threadmate is one of the most versatile threadlockers available on the market. An alternative to traditional liquid lockers which cure to form a hard bond, VC-3 is a proprietary blend of thermoplastic elastomer resins designed to remain flexible and absorb vibration. The combination of inert/non-reactive amorphous resins creates a tough, semi solid layer inside the threads of a mated joint. VC-3 damps the vibrational energy transferred between the threads of a mated fastener, preventing fastener loosening and loss of clamp load. These unique differences make VC-3 coated fasteners truly adjustable, removable, and reusable.

Vibra-Tite VC-4
Vibra-Tite VC-4 exhibits similar performance to Vibra-Tite VC-3 except it contains a base solvent of Ethyl Acetate. VC-4 is one of the most versatile threadlockers available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-4 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-4 coated fasteners truly adjustable, removable, and reusable.

Vibra-Tite VC-5
Vibra-Tite VC-5 exhibits similar performance to Vibra-Tite VC-3 except it contains a base solvent of Methyl Propyl Ketone. VC-5 is one of the most versatile threadlockers available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-5 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-5 coated fasteners truly adjustable, removable, and reusable.

Vibra-Tite VC-6
Vibra-Tite VC-6 exhibits similar performance to Vibra-Tite VC-3 except it contains a base solvent of Dimethyl Carbonate. VC-6 is one of the most versatile threadlockers available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-6 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-6 coated fasteners truly adjustable, removable, and reusable.

VC-3 Tape Instant Threadlocker
VC-3 Tape is a unique patent pending anti-vibration compound designed to prevent fastener loosening. Stretch and wrap VC-3 Tape around the threads of a fastener. VC-3 Tape is ready for immediate use with no drying or curing time required. After installation, a fastener wrapped with VC-3 Tape can be adjusted, removed, and re-used up to 3 times. (For small, fine thread fasteners, use liquid VC-3 Threadmate.)
