thickness. The ridges must not be ground off!
4.0 Flame-coating:
-
Go over the adhesive areas slowly with the flame.
-
Avoid flaming with the blue part of the flame.
-
Condensation water appears on the area that is still uncoated. The condensation water in the line of the flame
must evaporate completely.
-
Directly after flaming, coat the still hot adhesive areas (approx. 50
°
C) with primer.
5.0 Primer application:
-
Apply the primer with a brush, cotton wadding or similar.
-
Allow the coated surfaces to dry for approx. 5 minutes.
6.0 Adhesive application:
-
Processing temperature of adhesive cartridge 15
°
C - 25
°
C.
-
Do not use any compressed-air-operated cartridge guns.
-
Insert adhesive cartridge in cartridge gun, remove cap and allow both adhesive components to emerge. Strip
adhesive components uniformly and attach mixing tube.
-
Allow approx. 10 cm of mixed adhesive to emerge and then apply the mixed adhesive first on one side of the
adhesive area.
-
After applying the adhesive, check whether an adhesive component has emerged at the back of the cartridge. If
yes, break off the bonding procedure. Clean new component. Use new adhesive cartridge. Contact national
hotline.
-
Use a spatula to spread the adhesive over the adhesive area. Thickness of layer approx. 2 mm (dependent on
adhesive gap).
-
Potlife of mixed adhesive approx. 2 hours. A change of mixer is only necessary if over a period of 1 hour no
material has flowed through the mixer.
-
Join components and secure in position.
-
Remove excessive glue with paper or cloths.
6.1 Bonding in conjunction with repair parts (clamping pieces):
-
Bonding with clamping pieces is necessary in the event of structure damage. E.g. partial replacement engine
carrier.
-
Clamping pieces are special shaped parts for connecting new extruded section parts with the extruded section on
the body.
-
Clamping pieces expand when a special screw is inserted. This establishes a positive connection with the relevant
extruded section.
-
Ensure there is a sufficient gap between the adhesive and the threads for the expander screws (approx. 10-
15 mm).
