Loctite 406 Instant Adhesive

1. Clean & Dry. Wipe both surfaces with isopropyl alcohol to remove oil, dirt, and moisture. Let them dry completely. 2. Prime (If Needed). If bonding slick plastics like polypropylene (PP) or polyethylene (PE), apply a thin layer of LOCTITE® SF 770 Primer and let it evaporate fully. 3. Apply Sparingly. Squeeze one tiny drop onto one surface only. Do not spread it with cloth or cotton, and do not over-apply. 4. Press & Hold. Align the parts immediately and press them tightly together for 5 to 15 seconds.
