Description
Permabond® MH052 is ideal for the sealing of threaded joints. It is approved for use with natural gas and LPG for working pressure up to 20 bar (290 psi) and also for gaseous oxygen up to 10 bar (145 psi) and 60°C (140°F).
MH052 seals against gas, water, LPG, hydrocarbons, oils and other chemicals and will seal to the burst rating of the pipe. Unlike PTFE tape or hemp, Permabond MH052 will not shred or dry out, so it will provide a durable seal, helping to extend the life of the components.
Surface Preparation
Best results are obtained on bare metal surfaces. Remove paint, hemp fibres, PTFE tape or any other surface contamination from the bond area that could inhibit the cure. The use of a suitable solvent-based cleaner (such as acetone or isopropanol) is recommended to remove oil, grease, and other contaminants. Allow the solvent to evaporate before applying the adhesive.
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 around the circumference of the male thread (normally 1-2 threads back from the leading edge).
2) For taper/parallel threads ensure adhesive is positioned where the threads will engage fully. Gaps and cure times may be greater than expected with this joint configuration.
3) Ensure sufficient adhesive is applied to give a complete seal.
