Primed for Take-off
In general, 3M Scotch-Weld™ structural adhesive primers complement the 3M Scotch Weld™ Structural Adhesives portfolio and can be used to protect prepared substrates to be bonded. They facilitate "wet-out" of the primary adhesive agent to facilitate the bond between substrate and coating extrudate, then cured to enhance chemical resistance. Our adhesive primers help prepare the surfaces for the bonding agents and improve the conditions so that the adhesives are more effective and create stronger, longer lasting bonds.
