PERMABOND® MH052 Anaerobic Threadsealant Technical Datasheet Features & Benefits Mild Steel Stainless steel 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. Strength Development % Full Strength (steel) Excellent chemical resistance Pressure seal to burst rating of pipe No loose particles to clog valves Approved for use with gaseous oxygen WRAS listed for contact with wholesome (potable) water DVGW & BAM approval *Cure times are typical at 23°C. 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.

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.

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. % Strength Retained Temperature (°C) High Temperature Grades “Hot...
