Best Practices for Henkel E32
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 entrapped 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 6 hours until handling strength is achieved.
Full cure is obtained within 24 hours of adhesive application at room temperature, 25°C (77°F).
Note: The curing temperature may be raised to increase the cure rate of the adhesive.
Thoroughly mix Resin (A) and Hardener(B)in the correct proportion. Do not mix more material than can be applied during the 'usable life' of the product. Surfaces should be clean, dry and grease free before applying the adhesive. Where maximum strength is required then the surfaces should be shot blasted, or lightly abraded, in the presence of Loctite SIP.
Ideally Loctite E32 should be cured at temperatures above 15°C. Lower temperatures result in lower strength. The unmixed material should not be refrigerated.
Loctite E32 is approved to the Waters Byelaws Scheme as being suitable for contact with potable (drinking) water.
Unreacted resin & hardener can be cleaned using acetone, isopropanol or methyl ethyl ketone (MEK).
