8. Bond the body part.

   Information 

   • In order to ensure that the substance is completely mixed, apply a 30 mm long adhesive bead of fresh adhesive to a piece of cardboard before processing. 
   • The bonding material has an open time of → Working time: 60 min, within which the bonding material must be applied and the body component joined. Any resistance welding to be carried out in the area of the bonding must be done in this time. 
   • Do not load bonded parts until hardening is complete! 
   • If the contents of the cartridge are not completely used up, the processing nozzle should remain screwed onto the mixing nozzle. The thoroughly mixed bonding material hardens later in the processing nozzle and seals the adhesive components from the air. In the event of later processing, a new processing nozzle must then be used.
