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 7239 or 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 7458 or LOCTITE SF 7455 (see cure speed vs activator graph in TDS). Apply activator to one bond surface by spray, brush or dipping (not primed surfaces). Allow the activator to dry. 4. Application Apply adhesive onto one side/part. 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 7458 or LOCTITE SF 7455. Spray or drop activator onto excess product. Equipment For precise dispensing of small amounts of adhesive, the use of dispensing needles is recommended.
