Best Practices for Henkel Armstrong A-12 Epoxy Resin 2:3

*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.
