Huntsman Araldite 8579 Hardener 48 LB

Description

Araldite 8579 Hardener is the companion curing agent for the Araldite 8579 Epoxy system. It is formulated for balanced reactivity, reliable handling, and excellent resistance to heat and chemicals. Combined with the resin, it produces strong, dimensionally stable bonds for structural and industrial applications.

Araldite 8579 Hardener Key Benefits

• Designed to work with the Araldite 8579 Epoxy resin system
• Excellent chemical and moisture resistance for long service life
• Balanced cure profile for consistent performance across conditions
• Low shrinkage and strong mechanical properties
• Consistent viscosity for predictable processing

Araldite 8579 Hardener Applications

Araldite 8579 Hardener can be used with metals, composites, ceramics, and rigid plastics across aerospace, transportation, marine, fabrication, and general manufacturing. Common use cases include panel bonding, brackets and inserts, component assembly, and structural repairs that face heat, vibration, or aggressive media. The paired system supports controlled bond-line thickness and repeatable production quality.

Processing & Cure

Mix thoroughly with the resin (typical ratio: 100 parts resin : 30 parts hardener by weight). Process at room temperature for convenience or apply mild heat to accelerate cure and reach higher ultimate properties. Wet-out is dependable and open time allows precise alignment. Always prepare substrates by cleaning, degreasing, and drying; abrading can further enhance adhesion.
