1. Product Overview
Araldite® AW 139-1 / Hardener HW 5323-1 is a two-component, room temperature curing epoxy paste adhesive. It is thixotropic, gap-filling (up to 5 mm), and non-sagging. The adhesive provides high strength, excellent environmental and chemical resistance, and sustained performance under elevated temperatures. When cured, it forms a grey paste with robust bonding properties for metals, composites, and plastics.
2. Applications
Bonding metals, electronic components, and GRP structures.
Suitable for high-temperature or chemically aggressive service environments.
Effective for metal-to-metal and plastic-to-plastic bonding.
Available in cartridge form (Araldite® 2014-2) for ready-to-use application with dispensing tools.
