Best Practices for Henkel Armstrong A-34 Epoxy Resin
-
Surface Preparation
Surfaced to be bonded should be clean and dry. For critical applications refer to Bulletin No. 964
-
Application
Apply the adhesive to surfaces to be bonded (preferably both surfaces) and press together. Light clamping may be used to keep parts in position during cure.
-
Mixing
Thoroughly mix A-34 Part B with A-34 Part A in a clean, discardable container, suing correct mix ratio. Avoid introduction of excess air.
