Permabond A025 High-Temperature Assembly Adhesive – Anaerobic, Chemical-Resistant, and Suitable for Drinking Water
Permabond® A025 is an anaerobic curing adhesive specially developed for the permanent bonding and sealing of metal components. Whether bearings, gears, or threaded connections, this adhesive provides reliable and permanent fixation even under extreme conditions. With a temperature resistance of up to 200°C and excellent resistance to chemicals, Permabond A025 is ideal for demanding industrial applications.
The orange fluorescent formula facilitates quality control, while the medium viscosity ensures good workability on a wide range of metal surfaces. WRAS approval also allows use in drinking water applications. Curing is particularly fast on active metals such as copper or brass; for inactive materials, the use of Permabond A905 activator is recommended.
