Hardening Time

Do not move the vehicle before the adhesive has hardened. 

Check the degree of hardness of the adhesive with a fingernail.

If the adhesive cannot be pressed in any further with a fingernail, the vehicle may be moved (without engine force) for further processing applications (e.g. painting).

The procedure may be accelerated by using a radiant heater. Let the adhesive harden for 30 minutes at 85°C. The component can then be processed in the joint areas.

Vehicle strength for driving applications  is achieved after:

24 hours at a minimum object temperature of 23°C.

or 1 hour in the spray booth (spray booth temperature 80°C/object temperature 60°C).

When using radiant heaters, make sure that the object temperature does not exceed 85°C. Excessively high temperatures will destroy the adhesive.
