Best Practices for Henkel Armstrong A-1 Epoxy Resin w/ E Activator
-
Surface Preparation
The surface to be bonded should be clean and dry. For most applications mechanical and/or solvent degreasing is satisfactory. For some critical applications special chemical surface preparations should be used.
-
Mixing
Combine the two components in a clean, discardable container in correct proportions and mix thoroughly. Avoid the introduction of excess air, which reduces the effectiveness of the adhesive. In selecting the amount of adhesive to mix at one time the limited working life should be taken into account.
