Best Practices for Henkel Loctite E-04
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.
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.
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.
Unreacted resin & hardener can be cleaned using acetone, isopropanol or methyl ethyl ketone (MEK).
