Brand: Loctite Products
Threadlockers and thread sealants will not bond to certain "inactive" surfaces including aluminum, stainless steel, magnesium, zinc, black oxide, cadmium, and titanium. The use of a primer is required on these materials to "activate" the surface for bonding. Loctite® 7649 Primer N also speeds the cure time, especially in cold temperatures and when there is a gap between the mating parts. 4.5 oz aerosol can.
To use, begin by cleaning off any heavy grease or dirt from the surface using your preferred degreaser. Then do a final cleaning by spraying a generous coat of Loctite 7649 Primer N on the surface. Do not wipe off the Primer. Just allow the solvent to dry for about a minute, then apply the threadlocker, thrread sealant, or retaining compound. If the part is kept clean and dry in storage, you can wait up to one month before applying the compound. Parts stored longer or which become contaminated in storage should be re-treated prior to compound application.
