Withstanding Demanding Environments: The Araldite® AW 139-1/HW 5323-1 High-Performance Epoxy Structural Adhesive Solutio

In industries such as industrial manufacturing, transportation, and electronics, structural bonding requires not only high initial strength but also long-term stability and durability in complex and varying service environments. Huntsman Advanced Materials' Araldite® AW 139-1/HW 5323-1 is a high-performance, two-component epoxy paste adhesive specifically designed to meet such demanding requirements. Its exceptional high-temperature resistance, excellent chemical resistance, and strong gap-filling capability make it an ideal choice for industrial applications requiring long-term reliability.

• Exceptional Environmental Resistance: The cured adhesive can withstand high temperatures and exhibits strong resistance to water and a wide variety of chemicals (e.g., fuel, engine oil, brake fluid), ensuring bonded structure performance does not degrade in harsh environments.
• High Strength and Durability: It develops high-strength bonds upon curing at room or elevated temperatures, with typical lap shear strength on aluminum exceeding 14 MPa. Its design withstands continuous mechanical stress and vibration.
• Excellent Application Adaptability: The thixotropic paste consistency is non-sagging on vertical surfaces and can fill gaps up to 5 mm, making it highly suitable for bonding irregular or gapped components. A pot life of approximately 110 minutes (100g at 25°C) allows sufficient time for complex assembly.
• Convenient Packaging Options: In addition to traditional pails, the product is available in cartridges (Araldite® 2014-2) with static mixers, enabling efficient, waste-free mixing and application using standard dispensing guns.

1. Structural Bonding in Transportation Vehicles

   Application Description: Used in the manufacturing of buses, trucks, and rail vehicles for bonding aluminum or composite (GRP) body panels, reinforcements, partitions, and certain chassis components.

   Value Proposition: It replaces or assists traditional welding and riveting, reducing weight and avoiding thermal distortion. Its fatigue and corrosion resistance significantly enhance the vehicle's structural integrity and service life, effectively withstanding in-service vibrations and external weather challenges.

2. Industrial Equipment Repair and Manufacturing

   Application Description: Used for bonding wear plates for repairing machine tool guideways, sealing repairs for chemical pump housings, fixing corrosion-resistant linings in large tanks, and assembling components like housings for wind turbines.

   Value Proposition: Its chemical resistance (stable against various oils and solvents) and gap-filling capability up to 5mm make it excel in equipment repair and heavy equipment manufacturing, providing more uniform stress distribution and excellent sealing compared to mechanical fastening.

3. Potting and Fixing of Electronic Components

   Application Description: Used for bonding and fixing heat sinks, power modules, sensor housings, etc. Its excellent electrical insulation properties (volume resistivity up to 2.7E+15 Ohm.cm) provide reliable protection.

   Value Proposition: Beyond providing strong structural fixation, it protects sensitive electronic components from vibration, moisture, and chemical corrosion, ensuring the long-term stable operation of electronic systems in high-temperature environments.
