  • Best Practices for Henkel Armstrong A-12 Epoxy Resin 1:1

    *See Terms of Use Below

    1. 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)

    2. 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 curing.

    3. Mixing

      Thoroughly mix the A-12 Part B with the A-12 part A in a clean discardable container using correct mix ratio. Avoid the introduction of excess air.
