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.
