    Shelf Life Details Store product in cool, dry location, in unopened containers at a temperature between 8 C and 27 C (26 F to 80 F) unless otherwise labeled. Optimal storage is at the lower half of this temperature range. To prevent contamination of unused product, do not return any material to its original container. For further specific shelf life information, contact Application Engineering at (860) 571-5100.
    Shelf Life Temperature (°F) 46 to 81

  • 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).
