Surface Preparation

For best results from Permabond MH052,  surfaces should be clean, dry and grease free. An IPA wipe (Wipemaster Wipe 9) can be used to clean and to degrease surfaces. It is recommended to have a roughened surface of ~25μm in order to achieve high bond strengths. Surfaces such as zinc, aluminium and stainless steel could benefit from an anaerobic activator such as Permabond A905 or ASC10 to speed up the curing process.

Directions for Use

  1. First apply a continual bead circumferentially 1-2 threads from the leading edge to form a complete seal
  2. If working with taper/parallel threads, always ensure the adhesive is positioned where the threads will engage fully.
  3. Tighten as necessary.
