Technical Datasheet 4 Excellent chemical resistance 4 Pressure seal to burst rating of pipe 4 No loose particles to clog valves 4 Approved for use with gaseous oxygen DVGW Approval for Gas / WRAS Drinking Water Approval / KTW-BWGL Drinking Water Compliant 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). Permabond® 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. Typical Physical Properties of Uncured Adhesive Strength Development Chemical composition -Brass -Mild Steel -Zinc -Stainless steel Typical Curing Properties *Cure times are typical at 230C. Copper and its alloys will follow the faster cure while oxidised or passivated surfaces like stainless steel will tend towards the slower curve. Lower temperatures or large gaps will tend to extend the cure time. To reduce the cure time the use of Permabond® A905, ASC10, or heat can be considered. FOR PROFESSIONAL OR INDUSTRIAL USE ONLY. KEEP OUT OF REACH OF CHILDREN Handling time at 23°C/ 73°F. Copper and its alloys will make the adhesive cure more quickly, while oxidised or passivated surfaces (like stainless steel) will reduce cure speed. To reduce curing time, use Permabond® activator A905 or ASC10. Alternatively, increasing the curing temperature will reduce curing time.

Technical Datasheet Permabond® MH052 can withstand higher temperatures for brief periods (such as for paint-baking and wave soldering processes) provided the joint is not unduly stressed. 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. 4) Tighten the components with suitable tools....
