General Directions for Use
Minimum recommended bonding temperature : 10°C. Degrease the substrate with e.g. alcohol or spirit. (The substrate must be free of grease, moisture, dust, silicones, etc.). Remove the protective paper and press the tape firmly into contact with the substrate, with special attention to the edges. Preferably, allow substrate and pressure sensitive tape to stand for 24 hours after applying load.
