Product Description
ARALDITE® AW 139-1 / Hardener HW 5323-1 is a two-component, room-temperature-curing epoxy paste adhesive for structural bonding where elevated temperatures or aggressive service environments may be encountered. The thixotropic, non-sagging mixed adhesive fills gaps up to 5 mm and is suitable for bonding metals, electronic components, GRP structures, and other supported assemblies. A 100:50 mix ratio by weight or volume, approximately 110-minute pot life at 25°C, and specified lap shear strength above 14 MPa at 25°C provide a practical balance of application control and bonded-joint performance.
Key features
- Environmental resistance: Resistant to water and a wide variety of chemicals.
- Gap-filling paste: Thixotropic, non-sagging consistency supports gaps up to 5 mm.
- Controlled working time: Approximately 110-minute pot life for a 100 g mixed mass at 25°C.
Applications / Suitable for
- Structural bonding of metals
- Bonding electronic components
- GRP structures and assemblies exposed to demanding environments
