  • Best Practices for Henkel ESP311

    *See Terms of Use Below

    1. Surface Preparation

      Bondmaster ESP 311 bonds well to even poorly prepared metal surfaces. For optimum bond strength and durability, the substrate surfaces to be bonded should be clean and dry. Chemical treatment of metallic surfaces gives optimum durability, but a simple abrade and degrease process may often be adequate. Cleaning or degreasing of plastic and composite surfaces is generally recommended to remove mold release agents which may inhibit optimum bonding results.

    2. Clean-Up

      Unreacted epoxy can be cleaned using acetone, isopropanol, MEK or Glycol Ethers.
