Joining Process

Information 

• When the adhesive oozes out along the entire length of the joint on both sides, enough adhesive has been applied. 
• ml cartridge is sufficient for a flange length of approx. 5 m. 

Information 

Adhesive cartridges must only be used with piston-driven applicator guns.

Information 

Adhesive must be free of damage. Deformed adhesive must not be used.

1. Prepare bonding gun, > V.A.G 1628 - hand-cartridge gun  or > VAS 6648 - pneumatic gun  or > V.A.G 1761/1 - pneumatic cartridge gun  .
2. Press out adhesive without the mixing tube until both components emerge from the cartridge.
3. Fit mixing tube on the cartridge and check that adhesive comes out.

   Checking emerging adhesive

   1. 3.1  Make sure that the two-component adhesive is mix ed evenly in the mixing tube.
   2. 3.2  Before applying adhesive to the joints, apply a 10-20 cm long bead of adhesive to a paper towel or similar item and dispose of it later. The hardening process can also be checked using this bead.
   3. 3.3  Also apply a bead of adhesive approx. 10 cm long to a paper towel or similar item for the sample test.
4. Apply adhesive.
   1. 4.1  Apply adhesive to both flanges of the joints.

   3. 4.3  Areas without a cathodic-dip coating and bare body panels in cavities must be brushed or filled with structural adhesive.
5. Apply an additional bead of adhesive in the centre of the joint.

   Joining components

   1. 6.1  Assemble parts, secure them and join them within the specified processing time.

      The joining process must be performed immediately after applying adhesive in order to guarantee a high quality and reliable bond.

      Otherwise, the adhesive bead must be removed and pre-treatment of the surface and application of the adhesive must be repeated.

      The layer thickness of the adhesive following joining must not be more than > Layer thickness 1 mm  .

7. Remove excess adhesive.

   Removing excess adhesive

   1. 7.1  Remove excess adhesive with a clean cloth.
   2. 7.2  Give visible surfaces a final clean using a clean cloth soaked in acetone.

      Hardened material can only be removed by mechanical means.
