Summary: Loctite 7649 Metal Primer is a solvent-based activator and primer sold by Lavi Industries for use with Loctite 326 Metal Adhesive on stainless steel railing components. Lavi part number 00211 is sprayed or brushed onto the metal before the adhesive goes on. It speeds the cure on stainless steel, cutting set time from hours to minutes. Without primer, Loctite 326 bonds brass within minutes but can take overnight on stainless. It is used when assembling 304 and 316 stainless flush fittings, splices, and prefabricated posts with adhesive instead of welding. Lavi lists the two products together in its railing adhesive family, and both ship from US inventory.
