Permabond A1058 is a high-viscosity anaerobic thread sealant in paste form — developed for coarse metallic pipe threads with the highest pressure-tightness requirements. The bond allows alignment of components during curing.

With 300,000 mPa·s, A1058 is almost a kneading compound — it does not drip, does not run, and remains precisely where it was applied. This consistency allows components to be aligned even during curing — important for long pipelines with defined connection positions.

The thread sealant withstands pressures up to the burst limit of the pipe, making it suitable for high-pressure applications. The WRAS approval qualifies A1058 for potable water systems — for example, in drinking water and distribution networks.

SPECIAL FEATURE

Pressure-tight up to the burst pressure of the pipeline — the highly viscous paste with 300,000 mPa·s fills coarse pipe threads completely and permanently. Allows alignment of components during curing. WRAS approved for potable water.

Processing

1
Clean surfaces
Bonding surfaces must be clean, dry, and free of grease. Degrease with Permabond Cleaner A or a solvent (acetone, isopropanol). Rough surfaces (~25 µm) result in higher bond strength than polished ones.
2
Apply adhesive
Apply Permabond A1058 directly from the bottle — for through-holes, apply a stripe over the thread length; for blind holes, apply a few drops at the bottom. Do not touch the tip with metal surfaces (premature curing in the bottle).
3
Joining components
Insert the screws and tighten to the desired torque. For shaft-hub fits, assemble the components before the adhesive begins to cure.
4
Allow to cure
Anaerobic curing begins in the absence of air and upon contact with metal. Handling strength is typically achieved after 15 minutes, functional strength after 1 hour, and full strength after 24 hours at 23 °C.
5
Accelerate curing (optional)
On inactive surfaces (stainless steel, zinc, aluminum) or at low temperatures, Permabond A905 activator can be used — apply to one bonding surface, allow to flash off, then apply adhesive to the other side.

Important Notes

Not suitable for / Important notes
Suitable only for metallic pipe threads (curing under exclusion of air + metal contact). Not for oxygen or steam contact. For inactive surfaces (zinc, stainless steel), use A905 activator.
Storage
Store at 5 to 25 °C. Anaerobic adhesives lose their reactivity upon contact with metal — do not touch the tip of the bottle to metal surfaces, and do not pour adhesive back into the bottle.

Frequently Asked Questions about Permabond A1058

Practical application and design questions — answered by SILITECH.

Permabond A1058 is an acrylic (anaerobic) adhesive with a viscosity of 300,000 mPa·s (paste) and gap filling up to 0.5 mm. High-viscosity paste thread sealant — fills coarse pipe threads, pressure-tight up to the burst limit. Anaerobic adhesives cure in the absence of air and in contact with metal — ideal for tightly toleranced metallic joints.

Anaerobic adhesives such as Permabond A1058 remain liquid in the bottle (air contact, oxygen) and only begin to cure after assembly under exclusion of air and in contact with metal. Curing starts from the metal surface and progresses into the bond gap. The product cures quickly on steel and copper; on stainless steel and zinc, Permabond A905 Activator may be beneficial.

Difficult to disassemble — Permabond A1058 is high-strength (8 N·m breakaway torque). Disassembly typically requires heating the joint to 200 °C or more. Designed for permanent bonding.

Permabond A1058 is approved according to WRAS drinking water approval . These certifications qualify the product for the respectively specified applications — for example, direct contact with drinking water for WRAS and KTW approvals.

Permabond A1058 typically achieves handling strength after 15 minutes and functional strength after 1 hour at 23 °C on M10 steel. Final strength is reached after 24 hours. On inactive surfaces (stainless steel, zinc) or at low temperatures, the curing time is extended — Permabond A905 Activator accelerates the process.

Permabond A1058 is a high-viscosity thread sealant (300,000 mPa·s (paste) viscosity, 0.5 mm gap filling, 8 N·m breakaway torque). Permabond A129 is a medium-strength gel (gel, 0.5 mm, 12 N·m breakaway torque) — lower viscosity, medium strength. Both belong to the anaerobic Permabond A series.

The choice depends on the application: Permabond A1058 (high-viscosity thread sealant); Permabond A129 (medium-strength gel); Permabond A1044 (fast curing); Permabond A118 (high-strength threadlocker). For inactive surfaces (stainless steel, zinc, aluminum), additionally use Permabond A905 Activator to accelerate curing.
