Polymer adhesive LH055

for metalsingle-componentindustrial

Product Overview
Permabond LH055 is a PFAS-free, single-component anaerobic thread sealant formulated to provide a durable seal on both tapered and parallel metal threads. It cures in the absence of air between metal surfaces to form a resistant seal with good chemical resistance, while offering a relatively low breakaway torque for ease of future maintenance or disassembly.

Applications
Suitable for use on a variety of metals including steel and brass. Typical applications include plumbing systems, cooling circuits, pumps, valves and other threaded metal pipe connections requiring dependable sealing and straightforward maintenance.

Technical Characteristics

• Chemistry: Single-component anaerobic adhesive (cures between metal surfaces in absence of air)
• PFAS status: PFAS-free formulation
• Breakaway torque: Relatively low; specified example 8 Nm (70 in.lb) on zinc (facilitates disassembly with normal tools)
• Approvals: DVGW gas approval; KTW-BWGL and WRAS approvals for contact with drinking water
• Suitable substrates: Steel, brass and a wide variety of metals
• Typical applications: Thread sealing for plumbing, cooling circuits, pumps, valves and threaded metal pipe connections
• Viscosity: Optimised to provide full thread coverage (low strength variant in the LH055 designation)
• Performance: Good chemical resistance; designed to prevent thread seizure and allow future maintenance
• Physical form: Thread sealant (liquid/adhesive applied to threads)
