Huntsman Araldite AW 139-1 Epoxy Resin with HW 5323 Hardener 20 kg

Description

Huntsman Araldite AW 139-1 epoxy resin paired with Hardener HW 5323 is a two-component structural adhesive supplied in 20 kg packaging for production use. The Araldite AW 139-1 system is built for bonding metals, electronic components, GRP structures, and other substrates where elevated service temperature and a controlled chemical environment matter. Low outgassing makes it a fit for telecommunications and aerospace assembly work. The 20 kg supply suits continuous production cells.

What sets Araldite AW 139-1 apart in structural bonding

The cured AW 139-1 with HW 5323 bond carries higher temperature and chemical resistance than typical room-temperature epoxies. The grey paste consistency stays put on vertical and overhead surfaces and fills gaps up to 5 mm without sagging, which simplifies fixturing on large parts. Service exposure to water, fuels, solvents, and common industrial chemistries is well documented in the manufacturer technical data.

• Two-part epoxy adhesive, AW 139-1 resin with HW 5323 hardener
• Grey paste, non-sagging up to 5 mm gap fill
• High temperature and chemical resistance after cure
• Low shrinkage for dimensional stability on precision assemblies
• Strong resistance to water and a wide range of chemicals
• Low outgassing, suitable for electronics, telecom, and aerospace
• 20 kg packaging for production volume
• Room temperature cure with post-cure option for higher service temperature

Where the Araldite AW 139-1 system fits in production

Metal-to-metal bonding, electronic component encapsulation, GRP structural assemblies, and any specification calling for a controlled, low-outgassing epoxy. The 20 kg supply is sized for cells running ongoing production rather than one-off repair work. Pair with the proper surface prep, abrasion plus solvent wipe, to maximize adhesion on stainless, aluminum, and composite substrates. A post-cure step lifts service temperature and chemical resistance further.
