Permabond A1044 Anaerobic Threadlocker

Applications

• Lock and seal metal pipe connections offering very good resistance to even the most aggressive chemicals.
  
• A1044 can withstand higher temperatures than 150°C for brief periods than  (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55°C (-65°F) depending on the materials being bonded.
• This product is not recommended for use in contact with oxygen, oxygen-rich systems and other strong oxidizing materials. This product may adversely affect some thermoplastics and users must check the compatibility of the product with such substrates before using.

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 continuous bead circumferentially 1–2 threads from the leading edge.
2. Ensure sufficient is applied to give a complete seal.
3. For taper/parallel threads ensure adhesive is positioned where the threads will engage fully.Gaps, and therefore cure times, may be greater than expected with this joint configuration.
4. Tighten with normal tools.
