Permabond A025 High Strength Threadlock

Product overview

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.

Featured Properties

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

Surface Preparation

Though the anaerobic adhesives will tolerate a slight degree of surface contamination, best results are obtained on clean, dry and grease free surfaces. The use of a suitable solvent-based cleaner (such as acetone or isopropanol) is recommended. In general, roughened surfaces (~25μm) give higher bond strengths than polished or ground surfaces. To reduce the curing time, especially on inactive surfaces (such as zinc, aluminium and stainless steel), the use of Permabond A905 or ASC10 can be considered.

Directions for Use

1)Apply a circumferential bead; preferentially to the female component. Assemble with a twisting action.

2)For larger components use thixotropic products to prevent run off.

3)Take care to ensure adhesive does not enter ball races or other mechanisms.
