Best Practices for Henkel A-708
-
Surface Preparation
The surfaces to be bonded should be clean and dry (for critical applications refer to our suggested surface preparation procedures - Bulletin No. 964)
-
Application
Apply the adhesive to surfaces to be bonded (preferably both surfaces) and press together.
-
Mixing
Thoroughly mix the A-708 prior to use.
Avoid the introduction of excess air.
-
Curing
Light clamping may be used to keep parts in position during curing.
Cure as desired.
