Correct surface preparation is key before any bonding application, and the use of threadlockers is no different.
Loctite recommend the use of Loctite SF 7063 to degrease and clean the threaded components prior to application.
Loctite SF 7063 is a general-purpose product for cleaning and degreasing any kind of surface or machinery component before proceeding with a repair or assembly job involving Loctite adhesives. It is a solvent-based cleaner and the product leaves no residue. Loctite 7063 removes most greases, oils, lubrication fluids and metal cuttings.
All components should be dried before application of the adhesive.
Did you know that correct cleaning can improve the grip (adhesion) of the threadlocker by as much as 60%?
