Description
Araldite 2028-1 Hardener, 5 Gallon Pail is the hardener component for a transparent two-component polyurethane adhesive system. Pair it with the matching resin when the assembly needs a clear bond line, cold cure, and compatibility with selected metal, plastic, and glass substrates.
Araldite 2028-1 Benefits
- Transparent finished appearance helps reduce visible bond lines on display and lighting assemblies.
- Cold-curing polyurethane chemistry supports shop-floor bonding without a full oven cure cycle.
- Fast-curing profile is useful for production cells that need steady handling flow.
- Offers UV stability for applications exposed to light.
- Five gallon packaging fits batch dispensing, refill stations, and higher-volume production use.
This hardener is used as one side of a two-part adhesive, so the application process depends on the matching resin, mix equipment, nozzle selection, and surface preparation. Keep the components clean, meter them at the specified ratio, and apply an even bond line before parts are clamped or fixtured. For clear assemblies, trial bonds help confirm that the joint design, surface preparation, and cure conditions match the appearance target.
Common Applications
- Bonding clear or light-colored parts where adhesive appearance matters.
- Traffic light housings, LED assemblies, and display components.
- Metal-to-plastic and plastic-to-glass joints after proper surface preparation.
- Production dispensing into cartridges, meter-mix systems, or approved containers.
Compatible Substrates and Materials
- Metals named in the project test plan.
- Selected plastics where polyurethane adhesion has been validated.
- Glass and transparent assemblies requiring a clear adhesive line.
- Wood or mixed-material assemblies when approved by testing.
