How to use
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7070) to degrease and clean surfaces prior to applying the adhesive.
To improve adhesion on difficult to bond plastic surfaces, apply LOCTITE® SF 770 to the bond area by brushing or dipping. Avoid applying excess primer. Allow the primer to dry.
FAQ
Primer should be applied via brush or spray sparingly to any/all difficult-to-bond substrates that are being bonded.
