Instructions for Use:
1. Make sure that the surfaces to be bonded are clean, dry and free of contaminants before applying the adhesive.
2. Select the required band width by rotating the nozzle and positioning it between the area indicated on the plastic crown by Le H (L = approximately 2 cm – H = approximately 7 cm) and point the spray nozzle in the direction of the area to be adhesive.
3. Shake the container for about 5-10 seconds before use.
4. Keep the can about 12-18 cm from the surface to be adhesive. If the distance is increased by more than 20 cm, the spray band will tend to narrow.
5. For a homogeneous application, press the nozzle completely.
6. Apply a single layer of adhesive to the surfaces, allow to dry slightly for about 10-30 sec. and only then join the parts.
7. For edge rounding operations (pinching), gluing can be done up to 10 minutes after applying the adhesive.
8. To prevent clogging of the nozzle, it is recommended at the end of the work to purge the cylinder by turning it upside down and pressing the nozzle until the jet is free from adhesive.
