Best Practices for Loxeal 4580
-
Surface Preparation
Clean and degrease surfaces with Loxeal Cleaner 10 before applying the adhesive.
Some metals such as aluminium, copper and its alloys will benefit from light abrasion with emery cloth (or similar), to remove the oxide layer.
-
Application
Directions for Use: The adhesive should be dispensed from the cartridge via the nozzle supplied.
Apply the adhesive to one surface avoiding to entrap air.
Assemble parts applying enough pressure to ensure the adhesive spreads to cover the complete area to be bonded.
Use a jig / clamp to prevent parts moving during polymerisation.
-
Curing
Curing time is affected by type of substrate (heat transmission), and by gap to be filled. It will also depend on time needed by the adhesive to reach this temperature - for example, large assemblies or crowded oven will require longer to reach full cure.
Alternative methods for fast curing include induction, infrared lamps and hot air guns.
