  • Best Practices for Henkel Loctite E-04

    *See Terms of Use Below

    1. Surface Preparation

      For optimum bond strength on metal parts, the surface should be washed with a solvent or cleansing solution, abraded with an abrasive pad, and then rinsed with a solvent or cleansing solution. Glass surfaces should be cleaned with a commercial glass cleaner before bonding. Painted surfaces and plastic substrates should be abraded lightly and wiped clean.

    2. Application

      Thoroughly mix the resin and the hardener in a 1:1 ratio by weight or volume, taking care not to introduce excess air into the bulk material.

      The optimum method of mixing is accomplished via in-line static mixers with a minimum of 18 mixing elements.

      Once mixed thoroughly, to a uniform gray color

      i.e. no visible streaks, apply a bead of adhesive to one of the bonding surfaces.

      Mate the two substrates together and clamp the assembly for 2 hours until handling strength is achieved.

      Full cure is obtained within 24 hours of adhesive application at room temperature, 25°C (77°F).

      The curing temperature may be increased to facilitate full cure of the adhesive.

    3. Mixing

      For optimum performance, E04 should be mixed in exactly a 1:1 ratio. A reduction in adhesive properties will result from an incorrect mix ratio or incomplete mixing. Static mix nozzles should have a minimum of 18 mixing elements for optimum mixing of the epoxy.

      BONDMASTER E04 Part A & Part B should not be mixed in large quantities, as a vigorous chemical reaction will occur generating a significant amount of heat and vapors.

    4. Clean-Up

      Unreacted resin & hardener can be cleaned using acetone, isopropanol or methyl ethyl ketone (MEK).
