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) Shake bottle before use.
2) Prevent the tip from touching metal surfaces during application.
3) When working with through holes, dispense a bead of material across the contact length of the threads.
4) When working with blind holes, apply several drops down the threads to the bottom of the hole.
5) Assemble and torque the parts as necessary.
6) Replace lid to bottle to avoid contamination of remaining liquid adhesive.
