1. Preparation - Cleaning It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7063) to degrease and clean surfaces prior to applying the adhesive. 2. Preparation - Priming 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. 3. Preparation - Activation If cure speed is too slow, use appropriate activator LOCTITE® SF 7455 or LOCTITE® SF 7455. Apply activator to one bond surface by spray, brush or dipping (not primed surfaces). Allow the activator to dry. 4. Application Apply adhesive to one side or part.Recommended dispensing equipment: for precise dispensing of small amounts of adhesive, use dispensing needles. 5. Assembly Assemble parts immediately. The parts should be accurately located as the short fixture time leaves little opportunity for adjustment. Bond should be held or clamped until the adhesive has fixtured. Hint: if necessary, excess product can be cured by activator LOCTITE® SF 7455. Spray or drop activator onto excess product.
