Vibra-Tite VC-3 is a powerful locking and sealing coating for threaded fasteners that works on the principle of “friction through viscosity.” It utilizes a blend of acrylic resins to prevent fasteners from loosening — even under extreme vibration. Designed for use on external and internal threads of metallic and some plastics fasteners, Vibra-Tite VC-3 dries to the touch within minutes of application and coated parts are ready for assembly in just a few minutes. Pre-cleaning of parts is not required except for wiping off any visible oil, grease, or dirt for optimal performance.
