PERMABOND® A025 Anaerobic Retainer

Permabond® A025 is an anaerobic adhesive formulated to provide permanent locking and sealing of metal parts such as bearings, gears, studs and other threaded components. It has been designed for applications where joints have to withstand temperatures up to 200°C or where the maximum degree of chemical resistance is required. These features allow machining tolerances to be relaxed and mechanical locking devices to be eliminated, with consequent cost savings.

FEATURES AND BENEFITS

Excellent temperature resistance
Excellent chemical resistance
WRAS listed for contact with wholesome (potable) water
