Araldite 5052 Epoxy Resin System The Ultimate Bonding Solution for Aerospace and Advanced Industries

Araldite, a flagship brand under Huntsman Corporation, stands as a global pioneer in high-performance adhesive technologies. Since its inception in 1946 as the world's first commercial epoxy resin brand, Araldite has rewritten material engineering history through numerous groundbreaking innovations. The brand's legacy includes:

• 1955: Launched the first toothpaste-style household adhesive packaging, revolutionizing consumer access
• 1966: Pioneered structural epoxy use in architecture for Sydney Opera House's shell roof connections
• 1999: Became specified material for China's Shenzhou spacecraft control systems
• 2004: Enabled composite bonding for Airbus A380, the world's largest passenger aircraft
• 2010: Supported Beijing-Shanghai High-Speed Rail track slab engineering

Today, Araldite systems serve thousands of enterprises across aerospace, automotive, construction, and electronics, combining seventy years of polymer science expertise with cutting-edge R&D. The LY5052/Aradur 5052 system exemplifies this legacy, delivering German LBA (Luftfahrtbundesamt)-certified performance for mission-critical applications

The Araldite 5052 system is a two-component cold-curing epoxy composed of LY5052 resin and Aradur 5052 hardener. This formulation delivers an optimal balance of processability and performance:

• Low-Viscosity Processing (1000-1500 mPa*s for resin, 40-60 mPa*s for hardener): Enables effortless impregnation of carbon/glass fibers, suitable for Resin Transfer Molding (RTM) and filament winding
• Extended Pot Life (110-160 min for 100ml at 25°C): Allows large-scale component production without premature curing
• Intelligent Curing Profile: Achieves 60°C glass transition temperature (Tg) at ambient cure, upgradable to 120-134 °C via post-cure
• Outstanding Mechanical Properties: Post-cured laminates exhibit flexural strength of 440-490 MPa and tensile modulus of 33,100-39,100 MPa

• Aircraft Repair: FAA/EASA-approved for structural patching of composite fuselage and wings
• Glider Manufacturing: Certified by Germany's Luftfahrtbundesamt for primary structural bonding
• Space Systems: Applied in rocket engine assembly (Ariane 3) and spacecraft control systems

• Wind Energy: Bonds 60+ meter turbine blades, withstanding cyclic loads exceeding 10⁷ cycles at 110 MPa fatigue strength
• Transportation: Manufactures high-speed train components (e.g., Beijing-Shanghai HSL windshields)

• Composite Molds: Produces molds with >120°C heat resistance and ultra-low thermal expansion (CTE 71*10⁻⁶/K)

• Mixing Ratio:
  • By weight: LY5052 100 : Aradur 5052 38
  • By volume: LY5052 100 : Aradur 5052 47
• Packaging:
  • Resin: 25 kg/steel drum
  • Hardener: 19 kg/plastic drum (Standard set: 2 resin drums + 1 hardener drum = 69 kg/set)
